Known bugs

Main window and database

• Multiple screens: does not work in all the configurations
  Cause: Too many possible configuration possible (each version of Linux and Matlab handle this in a different way)
  Workaround: work only with your main screen

• Tree is not updated well and some nodes are missing
  Cause: Unpredictible order of execution of Java/Matlab operations
  Workaround: Press F5 to refresh

• Problems in the display of the figures or the colorbars, especially on 64bit machines or when working on a remote system (X-server, VirtualBox, Windows remote desktop connection...).
  Cause: This might be due to the many bugs of the OpenGL support of Matlab, that appear only with specific combinations of OS/Matlab version/video card.
  Workaround: Disable the OpenGL rendering. In Brainstorm main window, select menu File > Set preferences, and select this option. All the 3D views will be very slow and there will be no transparency, but it may solve all the problems.

• Colormap sliders for contrast / brightness do not work with versions of Matlab < 7.4
  Workaround: Manipulate the colormap by clicking on the colorbar and moving up/down (brightness) and left/right (contrast)

• Some user preferences are not saved in compiled versions
• Tree menu: "Group conditions" does not update all the filename links (in results files, linkresults files, etc.)
• Save figures as AVI movies: only available on Windows
• Popup menus and "Open file" dialog take a few seconds to appear on some XP systems. Unknown cause...

• Popup menus and "Open file" dialog may generate the following error:
  The class "BstFileSelector" is undefined. Perhaps Java is not running.
  Workaround: Restart Matlab.

• Navigator: may not work if more than one condition/subject opened at the same time, and next file do not have the same time definition.
  Only things that this prevents you to do is to review at the same time different raw files that were imported in small time blocks... So not a major issue...

Figures issues (recordings / results)

• Colormap menus do not work from the 3D figures with some versions of Matlab (eg. R2007a)
  Workaround: Use the Colormaps menu in the main Brainstorm window.

• 2D/3D topography of modelized data (Fsynth) are always display with EEG colormap, even it is MEG
• Modelized data / Residuals: no sensors selection available
• "Save image" may capture a blank image on Linux
• "Save file" do not check if file already exists on Linux

Computation issues

• OS_MEG (overlapping spheres) may crash when:

  • The scalp in not very well aligned with sensors
    Workaround: register them well...

  • The scalp surface is not very clean (some garbage inside the head)
    Workaround: do your scalp extraction with FreeSurfer

• Permutation tests do not work on "kernel only" results

Scientific issues

• Grand average computation does not weight the different subjects with the number of trials for each subject
• New t-tests and old t-test do not give the same results, because the processing of bad channels is different:
  • Old tests: reject a channel when it is bad at least for one file
  • New tests: reject a channel only when it is bad in all the files
