Brainsight 2.5.5 is released for all users

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’.
