We are happy to announce the release of Brainsight 2.4.6.

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

Minimum requirements:

• Mac OS X 10.11 El Capitan or later is required. For a free update, visit <https://www.apple.com/macos/how-to-upgrade/>. 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), 10.14.6 (Mojave), and 10.15.7 (Catalina).
• Mac OS X 10.10 (Yosemite) and earlier are unsupported.

Important Compatibility Note:

• If you are already using the Brainsight 2.5 beta, don’t install this version.
• macOS 11 Big Sur is coming out very soon, but do not upgrade your Mac yet, because Brainsight is not yet compatible with Big Sur.

Changes since version 2.4.5:

• The Vet Robot subject registration procedure no longer requires manually cropping the skull reconstruction, it is now done automatically.
• Vet Robot stereo calibration and subject registration calculations are now much faster.
• Judging the quality of the Vet Robot stereo calibration procedure is now easier because we now show a graphical representation of the quality of the results.
• SPM12 .mat files can now be loaded everywhere a 4×4 matrix can be loaded from file; notably this can be used for atlas space registrations.
• When exporting .txt files from the Session Review window, the option to snap samples to a reconstruction previously only snapped inwards but now it will now snap in either direction, thus working for samples created inside the head (due to use of ‘crosshairs offset’ slider for example).
• Fixed a bug where the NEURO PRAX impedance check failed to update the electrode colours.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.4.6 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You might also need to download “Support Files Human 1.5” and/or “Support Files Vet 1.3” 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’.

Feedback:

• Exporting .nirs files can now include the results of any analysis that was performed.
• Exported .nirs files now contain metadata indicating that centimetres are used for positional information. This will prevent Homer2 from having to ask.
• The Vet Robot Configuration window no longer shows a ring around the flange in the camera views because the concept does not apply to the newest hardware.
• The newest version of the FTDI device driver (2.4.4) is now installed (this controls communication with RS-232 serial devices like the Polaris camera and Magstim TMS stimulator).
• Improved compatibility with macOS 10.15 Catalina by supporting ‘notarization’. This eliminates the “Brainsight can’t be opened because Apple cannot check it for malicious software” error message.

We are happy to announce the release of Brainsight 2.4.2.

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

Minimum requirements:

• Mac OS X 10.11 El Capitan or later is required. For a free update, visit <https://www.apple.com/macos/how-to-upgrade/>. 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), 10.14.6 (Mojave), and 10.15.2 (Catalina).
• Mac OS X 10.10 (Yosemite) and earlier are unsupported.

Important Compatibility Note:

• Note: the project file format has changed vs version 2.3.x. Brainsight 2.4 can open documents created by older versions of Brainsight, but older versions of Brainsight cannot open documents created by Brainsight 2.4. Opening an old project will convert the project format, and the conversion cannot be reversed.

Changes since version 2.4.1:

• When performing coil (or tool) calibrations, relaxed the check for how much the calibration block and tool tracker moved (it became too strict in Brainsight 2.4, resulting in calibrations sometimes failing even when the trackers were reasonably still).
• When using the ‘target positioning tool’, targets are once again drawn semi-transparent (this broke in Brainsight 2.3.4).
• The driver for the KeySpan USB-serial adapter is no longer installed because it does not work well with recent versions of macOS. If you have the driver already installed (from a previous version of Brainsight), it won’t be uninstalled, so you can continue to use it, however, we recommend contacting us for a free replacement.
• The newest version of the FTDI device driver is now installed (this controls communication with RS-232 serial devices like the Polaris camera and Magstim TMS stimulator).
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.4.2 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You might also need to download “Support Files Human 1.5” and/or “Support Files Vet 1.2” if you have an older version. Brainsight will warn at launch if that’s the case.

We are happy to announce the release of Brainsight 2.4. This is no longer a beta release, and is recommended for all users.

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

Minimum requirements:

• Mac OS X 10.11 El Capitan or later is required. For a free update, visit <https://www.apple.com/macos/how-to-upgrade/>. 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), 10.14.6 (Mojave), and 10.15.1 (Catalina).
• Mac OS X 10.10 (Yosemite) and earlier are unsupported.

Important Compatibility Note:

• Note: the project file format has changed vs version 2.3.x. Brainsight 2.4 can open documents created by older versions of Brainsight, but older versions of Brainsight cannot open documents created by Brainsight 2.4. Opening an old project will convert the project format, and the conversion cannot be reversed.
• If you are running macOS 10.15 (Catalina), you may get a message like “Brainsight 2.4.pkg can’t be opened because Apple cannot check it for malicious software.” If so, instead of double-clicking to launch the installer, control-click it and choose “Open” from the popup menu.

Changes since version 2.3.12:

• Added various Homer2-equivalent NIRS analysis features:
  • Support for multiple conditions.
  • Onset creation:
    • From existing samples already created in the session window.
    • By pulse detection in auxiliary data (low to high, high to low, threshold with dead time).
    • By manual time entry of onsets.
  • Optical density calculation and visualization, both unfiltered and with low-pass, high-pass, or band-pass filtering.
  • Concentration calculation and visualization of HbO, HbR, and HbT for:
    • Whole recording.
    • Block averages, with optional error bars.
    • Fast and easy recalculation when adding/removing onsets, changing baseline parameters, etc.
  • Easy selection and visualization of NIRS data:
    • Clicking on 3D representation of optodes on subject head shows corresponding waveform data.
    • Clicking on waveform label selects corresponding optodes in 3D image views.
• Made many improvements to Vet Robot support:
  • Significantly improved the overall accuracy of the system.
  • Region painting of the skull in sessions is now both saved in the project and undoable.
  • In the Session window, camera image views can now be zoomed and panned like other views.
  • Vet Robot sessions can now be cloned.
• Made many improvements to Axilum Robotics support:
  • Added support for the Axilum Robotics TMS-Cobot.
  • The skin reconstruction is now shown in the Session>Axilum step.
  • Greatly improved performance of projecting targets to the skin reconstruction.
• Added support for the Polaris Vega® position sensor.
• The Session > Polaris window now shows the exact field of view shape for the Polaris Krios and Polaris Spectra, where previously it was showing the shapes of their respective predecessor models.
• Instead of a generic ‘diagnostic pending’ message, more exact messages are provided for various Polaris error conditions (ex: bump detected, battery fault, temperature high, etc.).
• If your Polaris’ bump detector is triggered, Brainsight itself can now clear the error, obviating the need for the NDI Toolbox application.
• If the Polaris reports a dead battery or a temperature error, tool tracking will now work regardless. (You should still schedule a repair of your Polaris, as tracking accuracy may be reduced.)
• In the Session>Perform window, changing the active coil/tool calibration (from the ‘driver’ popup menu) now disables/enables the corresponding Polaris tools. For example, changing from a calibration that uses CT-123 to one that uses CT-456 will stop the camera from tracking the former and start tracking the latter.
• Changed the legend in NIRS views to have a global wavelength toggle button, that applies to all pairs, instead of per-pair control of wavelength visibility.
• In 3D image views, clicking a tube that represents a NIRS pair now selects the corresponding channel in the legend of waveform views.
• Selecting a NIRS channel in the legend table or rectangles view now selects the corresponding NIRS tube in 3D image views.
• Selecting an EEG/EMG/ECG/EOG channel in the legend table now selects the corresponding electrode in 2D/3D image views.
• In sample-based waveform views, when selecting multiple samples, error bars can now optionally be shown for averages (for EEG/EMG/ECG/EOG and NIRS data).
• In sample-based waveform views, clicking a waveform now shows a tooltip that indicates which waveform the sample is from or if it is an averaged waveform.
• Waveform views now default to showing a better range of data in both the x and y axes.
• Creating an Assembly List from a .txt file now gives the option of linking it to an existing Cap Layout or creating a new Cap Layout.
• When creating a reconstruction, you can now choose to keep only the largest piece (as opposed to previously, where all pieces were kept). This can be useful for skin reconstructions, where you don’t want artifacts.
• Overlays can now be configured to colour values above/below the threshold to be either transparent (as previously) or to repeat the hi/low colour of the lookup table.
• When exporting samples into DICOM files, you can now optionally project the sample along its axis to the intersection of a chosen reconstruction (ex: the brain surface).
• The ‘Manual (AC-PC+scale)’ atlas space window now shows resizable lines (instead of a box) to scale the template to the subject head. This better indicates how it is meant to be used.
• Added marmoset, pig, and sheep atlases.
• Added much more information to the text file streaming feature. In addition to raw Polaris tool locations that it output before, it now logs when: the selected target changes, a TTL trigger occurs, a sample is created, the crosshairs move.
• Added buttons to the Targets and Session Perform windows to navigate up/down/left/right on a rectangular grid.
• Added a button to reorient the crosshairs to be perpendicular to a chosen surface.
• All threshold sliders now have text fields below them so that exact ranges can be specified.
• Added a new preference to disable sounds played when creating samples or sampling landmarks.
• Partly fixed a longstanding bug where reconstructions based on ROIs would always claim that re-computation was necessary, even though the ROI hadn’t changed. (This will still occur for re-opened projects though.)
• Fixed a longstanding but minor bug where the threshold mask in an ROI window did not exactly match the effect of flood fill.
• Fixed a longstanding bug where converting a sample to a target made all hidden targets become visible. Now the visibility of targets is unaffected.
• In an ROI window, the up and down arrow keys and up and down mouse wheel now move by exactly one slice, instead of by the ‘slice increment size’ of the Preferences window.
• In image views, the name of a landmark/target/sample can now be shown/hidden using a new button below the brightness/contrast slider.
• Changes to .txt format export:
  • The .txt file format has been changed from version 8 to 12 due to some minor changes to the file format. If you have scripts/code that reads such files, you may need to adjust them slightly.
  • When exporting EMG data, the time range used for peak-to-peak calculations is now included.
  • When exporting TMS stimulation information, the Magstim® BiStim2 inter-pulse duration and second power are now included.
• Fixed a bug where Magstim® BiStim2 inter-pulse duration confused µs versus ms.
• Trackpad gestures are now supported in image views. You can now zoom with a two-finger-pinch gesture, and rotate with a two-finger-rotate gesture.
• Greatly improved performance snapping targets, grids, and electrodes to a reconstruction surface.
• Improved performance working with the Polaris.
• Improved support for non-admin macOS accounts. An admin account is still needed to install, but non-admin users can now run Brainsight.
• Improved support for macOS 10.14 Mojave and 10.15 Catalina, particularly their ‘dark mode’ feature.
• Fixed miscellaneous bugs.

Download:

• Brainsight 2.4 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You will also need to download “Support Files Human 1.5” and/or “Support File Vet 1.2” 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’.

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.

Download:

• Brainsight 2.3.11 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
• You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.

Changes since version 2.3.9:

• The Session > Electrodes step is now shown for all TMS users, previously it was only shown if your serial number enabled the feature, but since so many of our TMS users use EEG also, we decided to enable it for everyone.
• The Session > Electrodes step can now be populated from a Cap Layout; similarly, a Cap Layout can now be created from the contents of the Session > Electrodes step.
• Assembly Lists can now be exported to the Brainsight .txt file format.
• Session subject registration matrices can now be exported from the Review window into a Brainsight .txt file.
• Shift-clicking electrodes in 3D views now allows selecting/unselecting multiple ones.
• Completely fixed a bug where scrolling through 2D slices with the mouse wheel would sometimes incorrectly show blank slices.
• Fixed a bug where the AC-PC-Box atlas space window would fail to redraw after pressing the Update button.
• Fixed performance and responsiveness problems when using the Axilum Robotics TMS-Robot.
• Improved performance working with large amounts of NIRS data: the waveform views should no longer fall behind data acquisition, though they may draw more slowly to keep up.
• Improved performance of live EMG waveform views, they now draw more smoothly.
• Fixed miscellaneous bugs.

Download:

If you are using macOS 10.13 High Sierra (or newer) and Brainsight does not recognise your Polaris camera, please check the following things:

• open the Polaris Configuration window
• does the ‘Polaris Status’ show ‘No serial ports found’? (Not some other message.)

If so, it could be that you did not grant access to the FTDI kernel extension (kext). Starting in macOS 10.13 High Sierra, Apple made a change that requires users to grant a one-time permission to kernel extensions. If you upgraded your Mac from 10.12 or earlier, and were successfully using your Polaris previously, permission should be automatically grandfathered.

The prompt for permission looks like this:

After this message appears, you have only 30 minutes to visit Security Preferences and approve.  Look for something like below:

If you don’t do this before the 30 minutes elapses, the easiest way to be prompted again is as follows:

• Open Terminal.app (not Console.app) to get a text prompt.
• Enter the command “sudo kextload /Library/Extensions/FTDIUSBSerialDriver.kext”, then enter the computer password at the prompt.
• From the Apple menu, open “System Preferences”, select “Security & Privacy”, then click “General”.
• Near the bottom you should see an “Allow” button, click it.
• Reboot the computer.

Fortunately, you need only grant permission once, and never again.
