Brainsight 2.3.11 is released for all users

We are happy to announce the release of Brainsight 2.3.11.

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 <>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against OS X 10.11.6 (El Capitan), 10.12.6 (Sierra), 10.13.6 (High Sierra), and 10.14.1 (Mojave).
  • Support for Mac OS X 10.9 and 10.10 remains, but is removed in the upcoming Brainsight 2.4; if you still use either, please upgrade soon.

Special note:

Changes since version 2.3.10:

  • Fixed a bug with MNI head based projects where the orientation of the displayed crosshairs position was slightly incorrect, meaning that samples created at that position were similarly wrong. In addition, when using an Axilum robot, moving to a target would arrive at an incorrect position. No such bugs existed with projects based on subject MRI.
  • The reconstruction+chamber clipping feature now works much better. Several crashes were fixed, and the results should now better match expectations.
  • Improved support for Retina displays in image and waveform views, they should now look much crisper, especially the text.
  • In the targets window, added the ability to create targets from a cap layout.
  • When choosing a cap layout or assembly list, you can now choose to snap it to a curvilinear-type reconstruction instead of only a surface-type reconstruction.
  • For TMS users only, in the targets window only, clicks on 3D reconstructions now default to orienting the direction normal to the skin reconstruction. As before, this can be changed with the “optimize traj. using” popup.
  • Fixed a crash when loading DICOM files that use JPEG 2000 compression.
  • Fixed a bug where using the “3D Crop Tool” sometimes didn’t actually select a reconstruction when clicked.
  • Fixed a bug where adding a grid to a session sometimes resulted in improperly sorted grid nodes.
  • Fixed a bug where the 3D crosshairs size was either too big or too small.
  • Fixed a bug in the session window where choosing a cap layout was impossible because the OK button was always disabled.
  • Fixed a bug accidentally introduced in 2.3.10 where support for very old Polaris cameras was broken.
  • A new text field was added to allow numerically specifying a grid node twist amount (instead of only a slider).
  • Fixed a crash where connecting to an Axilum robot could sometimes crash.
  • Added a button to download the internal logs from an Axilum robot (which is useful when debugging problems).
  • Fixed miscellaneous bugs.
