We are happy to announce the release of Brainsight 2.3.1.

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

Minimum requirements:

• Mac OS X 10.9 Mavericks or later is required. For a free update, visit <https://www.apple.com/osx/how-to-upgrade>. Contact us if you need to upgrade your Mac hardware.
• This version of Brainsight was tested against OS X 10.10.5 and 10.11.5.

Changes since version 2.3.1:

•  Samples can now be exported into DICOM files, either as a new overlay or as a copy of the anatomical.  Each sample is drawn as a sphere. The spheres’ voxel values can be either from the EMG peak-to-peak or specified explicitly.
•  Improved the MNI152 model head subject registration algorithm.
•  Improved performance when working with many hundreds of samples.
•  Fixed a bug where cloning a session would result in the clone showing the motor maps of the original session.
•  Fixed a bug where Brainsight Vet would incorrectly warn at launch that the Support Files were not installed.
•  Fixed a bug where exporting a .txt file from the Electrodes Recording window incorrectly stated the coordinate system as “Brainsight” when in fact the coordinates are relative to the subject tracker.
•  Fixed a bug where grid targets would sometimes be unreachable by the Axilum Robotics TMS-Robot.
•  You can now move the Axilum Robotics TMS-Robot’s arm and seat to their ‘welcome’ positions separately.
•  The 3D annotation shapes (Cone, Arrow, Brainsight) have been tweaked to have a thin projection line, helping to show the inwards direction.
•  The Targets, Perform, and Review windows now show overlays by default.
•  The Session Registration window now allows changing the crosshairs shape.
•  The Polaris Configuration window now shows the device serial number and date the camera was last re-characterized.
•  Fixed miscellaneous bugs.

Download:

• Brainsight 2.3.1 can be downloaded from our website here:<https://www.rogue-research.com/downloads.html>

We are happy to announce the final version (non-beta) of Brainsight 2.3.

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

Minimum requirements:

• Mac OS X 10.9 Mavericks or later is required. For a free update, visit <https://www.apple.com/osx/how-to-upgrade>. Contact us if you need to upgrade your Mac hardware.
• This version of Brainsight was tested against OS X 10.10.5 and 10.11.4.

Changes since version 2.2.15:

• Important: Brainsight 2.3 now requires Mac OS X 10.9 Mavericks or newer.  If your Mac is reasonably recent (~2007 or newer), you only need to update the OS, see Apple’s website.  If your Mac is older, it’s possible you might not be able to update your OS, in which case contact Rogue Research for other upgrade options.
• Note: the project file format has changed. Brainsight 2.3 can open documents created by older versions of Brainsight, but older versions of Brainsight cannot open documents created by Brainsight 2.3.
• Note: Brainsight is now installed directly in the Applications folder, no longer in a Brainsight subfolder.
• Added support for the Brainsight NIRS device.
• Added support for the Axilum Robotics TMS-Robot.
• Added support for using the MNI ICBM 152 average brain as the anatomical, for cases where you do not have a scan of the subject.  In this case, the subject registration procedure is different, and includes a new ‘scaling’ step in online sessions.
• An optional refinement of subject registration can now be performed in the Session > Validation step. This is often useful to make corrections to small registration errors.
• TTL triggers (ex: from our optional foot switch) can now be used during the subject registration procedure (useful for single operators).
• The ruler tool now works in 3D views, allowing measurement along any reconstruction surface.
• Added a new kind of bullseye view that is target-centric instead of coil-centric.  Both kinds of bullseye views now also show a twist angle.
• The session window has been reorganized, with several new steps added or changed:
  • IOBox – this step allows for configuration and testing of the IOBox and EMG pod. You can choose which triggers to use, how long of a dead time, and which EMG channels to record. Note that the option to trigger from high to low has been removed; all triggers are now low to high only. These settings are now remembered as part of the session, and different sessions can now have different options. This step also displays a live view of the data coming from the EMG pod, to help you ensure that electrodes are well attached.
  • NIRS – this step allows for configuration and testing of the Brainsight NIRS device.
  • Neuro Prax – this step allows for configuration and testing of the neuroConn NEURO PRAX® device.
  • Axilum – this step allows for configuration and testing of the Axilum Robotics TMS-Robot.
  • Electrodes – this step is now also available in offline sessions. Electrode positions can now be imported from more file formats. The file coordinates are converted to subject space by choosing either an atlas space or the anatomical’s world coordinates. Additionally, you can now optionally project the location of electrodes sampled with the pointer to the skin to compensate for the thickness of the electrode itself.
• Improvements to waveform views:
  • You can now zoom in by holding the command key and dragging. A box will appear, and its contents will become the full extent of the view. To zoom out, you must still use the buttons in the HUD or option-scroll with the mouse.
  • Multiple waveforms can now be viewed at the same time, staggered along the y axis, in the same view.  This replaces the ‘EEG Vertically Stacked’ view (now removed) and works not only for EEG but for EMG, ECG, EOG, and NIRS.
  • Waveform views can now be customized, specifically, you can show/hide channels.
    • The ‘Fit in Y’ button was renamed to ‘Fit All Y’, and a new ‘Fit Y’ button fits by looking only at the currently visible time range.
  • From Preferences, you can now customize colours for the background, axes, and waveforms themselves.
  • Inverted the option-mouse-wheel zoom shortcut to be consistent with 2D and 3D views.
  • You can now pan by using the mouse wheel.
  • You can now view the FFT (Fast Fourier Transform) and RMS (Root Mean Squared) of any waveform (EMG, EEG, NIRS)
  • Improvements to the legend (at the top-right of waveform views):
    • Can now be expanded or collapsed and overlapping or not, as needed.
    • Can now be scrolled when there are a lot of channels.
    • Provides a checkbox for every channel that can be toggled to show/hide that channel.
    • Provides a contextual menu to show/hide waveforms and to centre a waveform in the view.
• EMG improvements:
  • There is now a live display of EMG data.
  • Added support for baseline subtraction in live EMG views.  The Session > IOBox step now provides a button to compute a per-channel baseline (or you can specify them manually) and this value will be subtracted from all live EMG views.  This doesn’t impact data recording, only visualization.
  • Fixed a bug where motor map visualizations could not be created if all the peak-to-peak values were manually entered (not from our EMG Pod).
• EEG improvements:
  • When exporting electrodes in Session > Electrodes, you can now choose the coordinate system to use (for file formats that allow it).
  • Electrode orientation can now be exported/imported from text files (instead of only x, y, z).
  • Electrodes are now displayed with orientation instead of only as a point.
  • The Electrode Recording and Session > Electrode windows can now import electrode names and MNI positions from Brainsight .txt files.
  • When creating a new session by importing a Brainsight .txt file, electrodes are now also created for any electrode information in the file.
  • Electrodes are now listed in the session review window.
• When creating cortical targets, it is now easy to set their orientation to be optimal for placing a TMS coil on the scalp. Previously, clicking on a curvilinear reconstruction always set the orientation to be normal to the curvilinear reconstruction itself, now you can optionally specify a different reconstruction (usually the skin reconstruction) using the popup button under the AP/Lat/Twist sliders.
• The AP/Lat/Twist oblique crosshair angles can now be entered numerically in textfields, instead of only manipulated by sliders.
• During a session, Polaris tracking can now be disabled by toggling the ‘enable tracking’ checkbox. This is especially useful when working with NIRS, where the Polaris’ infrared emissions will cause interference.
• Better support for communicating with Magstim 200^2 and BiStim^2 stimulators. If the device reports an error condition, the status text is now shown in red. The BiStim2 is better supported with the pulse interval and second power now displayed and recorded as part of a sample.
• An atlas space’s 4×4 matrix can now be exported as a MINC .xfm file. This is especially useful when using our manual AC-PC-box method, as you can now export and use the exact registration in other software.
• Curvilinear reconstructions can now be cropped using the ‘3D Crop Tool’.
• Curvilinear reconstructions can now be exported as a folder of CAD files, one file per peel (this only gives the shape, not the colours).
• You can now change the opacity of curvilinear reconstructions.
• Surface reconstructions (ex: a skin reconstruction) can now be made with even more smoothness than before.
• When importing/exporting reconstructions to CAD files, atlas space coordinates can no longer be used, since they often involve a scaling component and would thus distort the shape/size of the reconstruction.
• In the session window, pressing left and right with the Apple Remote now changes steps.
• In the session perform and session review windows, a new optional table column is available that shows how a sample was created, ex: by TTL1, TTL2, etc.
• The file format of .txt files exported from the review window has changed slightly: EMG channels are now numbered starting at 1 instead of at 0 (to match how they are displayed in the user interface).
• Cloning a session now preserves more details, such as the view layout, view orientations, crosshairs position, custom views, etc.
• To accommodate different accents, the preferences window now allows you to specify custom words for ‘sample’, ‘next’, and ‘previous’ when using speech recognition.
• In 2D and 3D views, holding the command key and scrolling the mouse wheel is a new shortcut for panning.
• Added new region painting shortcuts: as before, when using the various painting tools, holding the option key toggles between paint and fill; now, holding the shift key toggles between paint and erase.  So by using option and shift, you can now, paint, erase, fill, and erase fill without having to switch tools.
• Fixed a bug where the curvature of rectangular grids was not behaving as intended. The maximum curvature now results in ‘tighter’ grids.
• In Preferences, the highlight colour used when selecting targets/landmarks/samples can now be customized (the default is still red).
• Various performance improvements: much faster waveform views, better handling of large datasets, faster rotation of 3D views, faster computation of atlas spaces, faster computation of automatic curvilinear, faster ROI painting.
• The newest versions of the KeySpan (3.0) and FTDI (2.3) device drivers are now installed (these control communication with RS-232 serial devices like the Polaris camera and Magstim TMS stimulator).
• Fixed miscellaneous bugs.

Known Issues (new to 2.3 vs 2.2.15):

• ‘Save As’ can sometimes cause crashes, and so has been removed for now pending a complete fix.  (There is no problem with regular ‘Save’.)
• If you have both a Polaris and Magstim device connected to your Brainsight Mac, one or the other sometimes may not be detected.  If this occurs, just use the “Reset Polaris” or “Scan” buttons.
• The user manual is not yet fully up-to-date with the software.

Download:

• Brainsight 2.3 can be downloaded from our website here <https://www.rogue-research.com/downloads.html>
• You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter Serial Number’.
• Make sure to also download and install the newest “Support Files” (also newly released).  If your Support Files are out of date, Brainsight will warn you at launch.

We are happy to announce the availability of Brainsight 2.2.15.

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

Minimum requirements:

• Mac OS X 10.6 Snow Leopard is the absolute minimum version supported, but is strongly discouraged because it has a bug that can cause project saving to fail.
• Mac OS X 10.9 or later is strongly recommended. For a free update, visit https://www.apple.com/osx/how-to-upgrade/.

Changes since 2.2.14:

• Fixed a serious but unlikely bug where opening a pre-2.2 format document could become corrupted if you did not save the document after opening and converting it to 2.2 format.
• Fixed a bug where NIfTI sforms were incorrectly read, resulting in the displayed or exported world coordinates being incorrect. This is fixed both when opening old documents and creating new ones.
• Importing EMG data from a .txt file to create a new session now tags the data with the EMG amplifier pod version set in the preferences. This is necessary to prevent subsequent opening of the document from thinking the data needs to be corrected (which 2.2.13 and 2.2.14 would do).
• Fixed a bug, on OS X 10.10 Yosemite only, where activating the speech recognition feature often caused a crash.
• Fixed miscellaneous bugs.

Note to 2.3 beta users:

If you are already using a beta version of Brainsight 2.3, you should stay with that and ignore this email.

Download:

You can download 2.2.15 just like any version of Brainsight, from our website here:
https://www.rogue-research.com/downloads.html

You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter Serial Number’.

Installation:

We are happy to announce the availability of Brainsight 2.3b17.

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

** Minimum requirements **:
– Mac OS X 10.9 Mavericks or later is required. For a free update, visit <https://www.apple.com/osx/how-to-upgrade/>. Contact us if you need to upgrade your Mac hardware.
– Important: this is the first version to no longer support OS X 10.8 at all.
– This version of Brainsight was tested against OS X 10.9.5 and 10.10.4.

** Changes since version 2.3b16 **:
– Fixed a few bugs converting older documents.
– Fixed a bug where the installer did not always add Brainsight to the dock.
– Fixed a performance issue where moving the crosshairs in some image views was very slow.
– The AP/Lat/Twist oblique crosshair angles can now be entered numerically in textfields.
– Changed the colours of NIRS electrodes in the session windows.
– Clicking on a waveform (to pop up its name) now works in staggered mode too.
– Fixed a bug where the brightness/contrast slider was sometimes disabled in the overlays window.
– Fixed miscellaneous bugs.

** Known Issues (also in 2.3b16) **:
– In any given session, you can start and stop NIRS acquisitions as many times as you want, but only the data associated with the most recent ‘start’ (from either NIRS or Perform step) will be preserved. Older data will be discarded (it will warn first).
– The checkboxes in the waveform legend view and view customization window do not work properly in non-live waveform views, and should not be used.
– Brainsight can become slow when drawing NIRS acquisitions that are both large (more than a hundred channels) and long (upwards of tens of minutes). This is especially the case when visualizing all the channels simultaneously and for the whole time range. To avoid this, we recommend using staggered mode visualization with a moderate number of channels.
– Very large NIRS acquisitions can cause a crash. Brainsight will warn when your parameters are such that this might happen.
– The legend does not show EMG peak-to-peak values as it did in 2.2.x.
– Some very old IOBoxes (with the low voltage version LabJack) are not properly supported, and using TTL triggers may not work.
– The user manual is not up-to-date with the software.

** Known Issues (new to 2.3b17) **:
– None.

** Download **:
– Brainsight 2.3b17 can be downloaded, just like any version of Brainsight, from our downloads section here
– You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter Serial Number’.

** Feedback **:
– Please report any and all bugs, feedback, suggestions, etc. to <support@rogue-research.com> or by phone at +1-866-984-3888 (Canada & USA) or +1-514-284-3888.

Changes since 2.2.13:
– Added support for model 3 of our EMG Pod amplifier. Unfortunately, there’s no way for Brainsight to detect which model you have connected and so you must indicate to Brainsight by choosing your model in the Preferences window. As of today, everybody has model 2, but we are starting to make model 3 available to customers that want the retrofit.
– Fixed a bug where exported LOCATOR .elp files were not correctly formatted, resulting in problems importing them into other software.
– Fixed a bug where newer versions of the Keyspan driver were incorrectly detected as old, resulting in a warning at launch.
– Fixed miscellaneous bugs.
