We are happy to announce the release of Brainsight 2.5.5.

Before proceeding with this update, please read the following important information.

Minimum requirements:

• macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <https://support.apple.com/macos/upgrade>. Contact us if you need to upgrade your Mac hardware.
• This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7.6 (Monterey), 13.7.1 (Ventura), 14.7.1 (Sonoma), and 15.1.1 (Sequoia).
• Mac OS X 10.12 (Sierra) and earlier are unsupported. Support for 10.13 and 10.14 will be ending soon.

Changes since version 2.5.4:

• Made substantial improvements to Vet Robot tool calibration. The workflow is mostly the same except that you no longer need to identify the tool tip and shaft in both cameras simultaneously, you can instead do so in one camera at a time, which is helpful as the camera field of view is small and it can be hard to position a tool to be visible in both simultaneously. The algorithm that calculates the tool calibration is also much improved, giving more accurate tool calibrations.
• Improved Vet Robot tool-relative movement user interface to be more intuitive, and consistently move and rotate the tool around its axes: injection/retraction, left/right, forward/backward. Previously, the behaviour was not predictable.
• Vet Robot target reachability checks now have the option of checking that not only is the target itself reachable, but that a few millimetres deeper is also reachable. A new textfield in the Perform window allows setting this amount.
• Improved Vet Robot stereo calibration for small animal systems, to better cover the cameras’ field of view.
• Fixed a rare bug where Vet Robot stereo calibration could get stuck in an infinite loop.
• When importing targets from a text file, if the coordinate system name is set to “Relative”, the positions in the file can be interpreted as relative to another (already-existing) target.
• Fixed a bug where projects based on a SimNIBS .gmsh file could get the NIfTI sform and qform confused and result in an error message when invoking BabelBrain to perform a TMS simulation.
• Fixed a bug where Polaris tool tracking could sometimes show the subject tracker move with respect to the subject’s head. This was merely a visual glitch, and did not affect correctness.
• Improved performance working with many targets (example: big grids).
• Improved performance working with many electrodes (example: big EEG/NIRS caps).
• Improved performance opening .dxf files.
• The Polaris firmware version number is now shown in the Polaris Configuration window.
• In waveform views, when in staggered mode, you can now click a waveform to get a tooltip showing the channel name.
• Fixed a crash opening corrupt project files.
• Fixed a bug where recalibrating a NIRS block would program an incorrect version number into the block’s memory.
• Fixed a bug where the bullseye view would show a TMS coil in the background when a fUS tool was being used.
• Fixed a bug where the Vet Robot firmware version number would sometimes be displayed incorrectly.
• Fixed a bug where changing a sample’s EMG peak-to-peak value or its “contribute” checkbox would fail to refresh the sample’s colour in 2D and 3D views.
• Fixed a bug where changing the time index in a 4D overlay would sometimes fail to refresh 2D and 3D views.
• Fixed a bug where, if there were multiple surface reconstructions, changing the colour or other attribute of one would sometimes fail to refresh 3D views.
• Fixed a bug where, if there were multiple curvilinear reconstructions, changing the peel depth of one would sometimes fail to refresh 3D views.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.5 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.
• You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.

Rogue Research invites you to join us at the 2024 annual meeting of the Society for Neuroscience, Sunday October 6–Wednesday, October 9, at McCormick Place, Chicago, IL, USA where we will be exhibiting at Booths 578 & 579. Our Montreal- and US-based team will be on hand to demonstrate the latest technology in human brain stimulation and veterinary image-guided neurosurgery, including advancements in robotics, next-generation Transcranial Magnetic Stimulation, and an early look at our Elevate platform for remote delivery of protocols for clinical trials and treatment. We’ll also be offering training and Q&A sessions for users wishing to speak to our team of experts. We look forward to connecting with the neuroscience community in Chicago!

We are happy to announce the release of Brainsight 2.5.4.

• This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7.5 (Monterey), 13.6.7 (Ventura), and 14.5 (Sonoma).
• Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.3:

• Moved some user interface controls from the bottom to the top of the window, namely the 3D Crosshairs and Driver popup buttons. This gives more vertical space for images and makes the contents of the popup menu less likely to overflow.
• Added a new option in the Trigger Options window to allow creating samples even when the relevant Polaris tools are not visible (by default samples cannot be created when, for example, the coil tracker is not visible.)
• Now default to looking for SimNIBS 4.1 (newest at time of writing), instead of 4.0. If you have an older (or newer) version, adjust the path in Brainsight > Settings.
• Added a fourth set of tool-relative Vet Robot movement controls that only have buttons to inject and retract the tool. The controls that allow the more dangerous tool-relative rotations are now separated in a different pane.
• No longer allow Vet Robot to move to a marker-type target, only to trajectory-type targets. This is a safety precaution because, although markers technically have an orientation, it’s not displayed, and so the robot risks moving in an unexpected direction.
• Fixed a bug where Vet Robot subject registration would fail if the skull reconstruction was not watertight and consisted of several disjoint pieces and one of the initial registration landmarks was touching a secondary piece.
• For Vet Robot sessions, the default threshold range in the Validation step was tightened from 0.5 to 0.3 mm, reflecting recent improvements in system accuracy.
• Made various improvements for Axilum Robot / Cobot support:
  • An error message is now shown if the Cobot is not in MCP (manual control panel) mode.
  • Added functionality to switch Cobot sides.
  • The force sensor check procedure must now be redone if the coil is changed, or if two hours has elapsed.
  • Coil names are now partly anonymized, to no longer reveal if a sham coil is being used (to help with blind studies).
  • Extended the range of the contact sensor sensitivity.
• The Polaris Lyra is now configured to track at 30 Hz instead of 20 Hz.
• Fixed a bug where a bumps to a Polaris were not reported.
• Fixed a bug that could result in a failure to read some valid NIfTI files, for example those generated by BabelBrain.
• Fixed a bug where vector field arrows (for TMS simulation for example) sometimes did not display when then should have.
• Fixed a bug where 4D datasets with exactly 4 time components would be interpreted and drawn as vector fields.
• Added a new fUS transducer option for 3D Crosshairs shape.
• Added a new button next to the scene selection popup menu to quickly customize a view.
• A TMS coil is no longer shown in bullseye views when the selected tool calibration is fUS-type.
• Creating a surface/skin reconstruction is now about 25% faster.
• Creating a curvilinear reconstruction is now about 35% faster.
• Fixed various crashes that could occur opening corrupt files.
• Fixed miscellaneous bugs.

Join Rogue Research at the 30th Annual Meeting of the Organization for Human Brain Mapping (OHBM) in Seoul, South Korea this June 23 –27, where we will be exhibiting at Booths 407 & 408.  In addition to  demonstrating the latest advances in image-guided brain stimulation and veterinary neurosurgery, we look forward to speaking with the many users of our technology and gaining feedback from the field. Rogue Research shares OHBM’s mission of advancing the understanding of the anatomical and functional organization of the human brain, working with researchers to provide the best tools to achieve their research goals. 

Our team will be available to discuss both hardware advances including robotics for human and animal research, and software updates that integrate state-of-the-art modeling to assist in planning an image-guided study. We look forward to connecting with you in Seoul! 

We are happy to announce the release of Brainsight 2.5.3.

Before proceeding with this update, please read the following important information.

Minimum requirements:

• macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <https://support.apple.com/macos/upgrade>. Contact us if you need to upgrade your Mac hardware.
• This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7 (Monterey), 13.6 (Ventura), and 14.3 (Sonoma).
• Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.2:

• Brainsight can now simulate the acoustic effect of transcranial focused ultrasound (fUS) at a target location. It does this by interacting with BabelBrain, a third party software that must be installed separately. The Targets window now allows invoking BabelBrain, wherein simulation parameters can be set. The resulting simulation appears overlaid in 2D and 3D images, and can be customized from the Inspector window.
• When writing to our .txt file formats, we now use slightly different coordinate system names for NIfTI files, which may require updating code that reads these files. The coordinate system name now includes whether it’s from the file’s sform or qform. So, for example, where we used to use a string like “NIfTI:Scanner” we now use “NIfTI:Q:Scanner”. For this reason, exported .txt files increased from version 13 to 14, and .txt files created by streaming increased from version 6 to 7.
• Improved performance when creating hundreds of samples. There should be noticeably less latency between the trigger that creates a sample and its appearance in the application.
• Substantially improved accuracy of Vet Robot subject registration, thus improving accuracy results overall.
• Fixed a bug, introduced only in 2.5.2, where selecting two or more samples was not showing the average waveform for EEG and NIRS views (but was for EMG views).
• Fixed a bug where EMG waveform views sometimes did not show the visual indication (crosshatching) of when a waveform has exceeded the EMG pod device’s maximum range of 2.25 mV.
• Fixed a bug in EMG views where the line indicating the EMG latency would sometimes not redraw after the time range was changed (with the green vertical bars).
• Fixed a bug where electrodes could still be clicked in 3D views, even when all electrodes were hidden.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5.3 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.

• Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.1:

• Added calculation and display of EMG latency using the SHTE algorithm (by Šoda, Vidaković, Lorincz, Jerković, and Vujović). The Perform and Review windows now have a new optional table column that can show the latency for each sample. In addition, waveform views now draw a vertical line at the latency time. This line can be dragged to adjust the automatically computed value if it seems incorrect. Latency can also be streamed to a .txt file from the Perform window, and exported to a .txt file from the Review window.
• Each surface-type reconstruction can now be configured to participate in overlay blending or not. If the option is off, overlays will never be blended on that surface. If the option is on, overlays will be blended atop that surface, provided the overlay is enabled in the Inspector window (as usual). This option is off by default.
• A tool calibration’s 4×4 matrix can now be exported to a MINC .xfm text file.
• The Vet Robot can now be moved relative to the currently used tool.
• The Session Polaris window now allows selecting the Polaris, and also has a button in bring up the Polaris Configuration window.
• More windows now have the option of showing the crosshair’s numerical coordinates (at the bottom right).
• Fixed a bug where some projects with corrupt NIRS data would fail to load.
• Fixed a longstanding bug where the brightness/contrast slider did not work in the Curvilinear From Overlay and Surface From Overlay windows when an overlay was used as the source of the reconstruction.
• Fixed a bug where Brainsight would not automatically connect to a Polaris, even if it was detected.
• Fixed a bug where some image views would stop drawing after Brainsight was running in the background.
• Fixed a crash creating motor maps on old Macs with Nvidia GPUs.
• Improved performance creating motor maps on Macs with Apple Silicon processors.
• Fixed several crashes that could occur when opening corrupt files of various formats.
• Fixed miscellaneous bugs.

• This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.4 (Big Sur), 12.6.3 (Monterey), and 13.2 (Ventura).
• Mac OS X 10.12 (Sierra) and earlier are unsupported.

Important Compatibility Note:

• The project file format has changed. Brainsight 2.5 can open documents created by older versions of Brainsight, but older versions of Brainsight cannot open documents created by Brainsight 2.5.

Changes since version 2.4.11:

• Brainsight can now simulate the induced electric field due to a TMS stimulation at a target location. It does this by interacting with SimNIBS, a third party software that must also be installed. The Targets window now allows associating a TMS coil model and stimulation strength with each target. The resulting simulation appears overlaid in 2D and 3D images, and can be customized from the Inspector window.
• 3D reconstructions (like the skin reconstruction) are now coloured by blending any enabled overlays atop the reconstruction’s own colour.
• Overlays now support time series data (though only from NIfTI and MINC2 files, not other formats). The Overlays window and Inspector window now have a new slider to choose the time offset.
• Very large datasets (with more than 2^31 voxels) can now be used.
• Made various accuracy improvements to Vet Robot stereo calibration and subject registration, resulting in more accurate targeting during surgery.
• In the Session Perform window, creating new samples is now disallowed if the relevant Polaris tools are not visible.
• In the Session Perform window, the ‘stream to file’ feature now includes EMG waveform data and the coordinate system for selected targets and created samples.
• In the Session Perform window, the ‘Sample Now’ button is now disabled if the required tools are not visible to the Polaris camera.
• When working with the Axilum robot/cobot, a new ‘scalp offset’ distance can be specified to keep the TMS coil a few millimetres above the scalp to account for the thickness of an EEG cap for example.
• EMG waveform views now visually indicate when a waveform has exceeded the EMG pod device’s maximum range of 2.25 mV.
• Added support for the Cornell University (Johnson, Philippa J; Barry, Erica F) canine atlas.
• Fixed various bugs with some DICOM datasets, where images would appear split in half, have gaps, or have missing slices.
• Fixed a longstanding bug where reconstructions based on ROIs would claim that re-computation was necessary, even though the ROI hadn’t changed. (This was partly fixed in 2.4, but still occurred for re-opened projects.)
• ROIs can now be created by importing from a medical image file (DICOM, NIfTI, MINC, etc.).
• Fixed a bug in the ROI window where the pencil and eraser tools would not work correctly at the edge of view, especially when moving the mouse quickly.
• NIRS waveforms can be imported from a .nirs file, thus allowing importing data from other manufacturers’ NIRS devices.
• Fixed a bug (introduced in Brainsight 2.4.11) where the SD.SrcPos and SD.SrcPos3D fields in exported .nirs files were swapped.
• Fixed a bug (introduced in Brainsight 2.4.5) where the SD.SrcPos field in exported .nirs files were in decimetres instead of centimetres. (The SD.SrcPos3D field was exported correctly in millimetres though.)
• Assembly Lists and Cap Layouts can now be created by importing from a .nirs file.
• Calibrating a TMS coil or other tool now allows for the tool tracker and calibration tracker to move together (relative to the camera), instead of failing if either tool moved relative to the camera.
• Polaris tool visibility status now uses a larger coloured area, making it more visible from father away.
• The enabled/disabled state of Polaris tools in the Polaris Configuration window are now remembered across quit/relaunch.
• Landmarks, targets, electrodes, and samples can now be clicked in 3D image views to select the corresponding item in the related table view.
• Targets can now be exported to a text file from the Targets window (export was previously possible, but only from the Session Review window).
• In the Targets window, if a reconstruction is chosen in the ‘optimize traj. to’ popup menu, clicking in 2D views no longer reorients crosshairs.
• Exporting curvilinear reconstructions in the PLY format now includes the voxel values in greyscale, whereas previously no colour was exported, only the shape.
• When exporting reconstructions as STL, VTK, and PLY you can now choose between the ASCII and binary variants of these file formats.
• When importing a reconstruction from file, the object can now be placed relative to a chosen target (useful for placing chambers for example).
• The crosshairs in 2D image views now have a small gap in the middle so as not to obscure the very thing being targeted.
• Wherever 4×4 matrices can be imported from a file, a new file format is now supported namely plain text files with 16 numbers within.
• The crosshairs offset slider now allows a large range.
• When opening a project file, if there are referenced external files (datasets, CAD files) that can’t be found, the dialog that asks to find them now (by default) disables files with different names, thus making it much easier to find the correct file.
• A new preference allows changing the colours of the bullseye views, especially useful for colour blind users.
• A new preference allows changing the font size of the bullseye views.
• A new preference allows specifying default EMG baseline and trial durations that will be used when creating new sessions.
• Native support for Apple Silicon processors.
• Improved support for macOS 11 Big Sur, macOS 12 Monterey, and macOS 13 Ventura.
• Various performance improvements:
  • Exporting DXF files is now much faster, especially for large reconstructions.
  • Updating an atlas space template overlay is now much faster.
  • Reorienting the anatomical dataset is now much faster.
  • Creating curvilinear reconstructions is now much faster.
  • Creating skin and other surface reconstructions is faster.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.5 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.
• You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.
