= Known bugs = == Main window and database == * "Java heap space" error in Matlab. <
>__Workaround__: In the Matlab preferences, increase the Java Heap Space memory. * Brainstorm gets very slow after a while, you have to restart Matlab to make it work again. <
>__Workaround__: Increase the Java Heap Space memory. * Automatic updates crash while downloading the new software version. <
>__Workaround__: Increase the Java Heap Space memory. * Any error related with the function "fminsearch"<
>__Cause__: You have a toolbox in your Matlab path, such as EEGLAB, that redefines the basic Matlab function "fminsearch".<
>__Workaround__: From the Matlab preferences: Remove the folder containing this other fminsearch function from your static Matlab path, or remove entirely EEGLAB from your path. * 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 * 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. == Figures and display == * 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__: Change the OpenGL rendering properties. In Brainstorm main window, select menu File > Edit preferences, and select "software" or "disable". All the 3D views will be very slow and there will be no transparency, but it may solve all the problems. * Mouse wheel operations (zoom, scroll, change channel gain) do not work on older Matlab versions<
>__Cause__: Support for mouse wheel was introduced in Matlab 7.4 (R2007a), so there is no way to get the wheel events on previous versions.<
>__Workaround__: Upgrade Matlab or run the compiled version of Brainstorm. * 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. * 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) * "Save image" may capture a blank image on Linux and MacOS (functions getscreen and getframe do not work properly on many systems) == Computation issues == * Importing surfaces for an MRI that was re-oriented manually: surfaces are not properly oriented.<
>__Workaround__: Use an MRI that is already properly oriented (BrainVISA and FreeSurfer re-write the MRI in a good orientation before processing them). * 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
