= 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 * 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: "File > XTerm" does not work with all the linux distributions * Tree menu: "Group conditions" does not update all the filename links (in results files, linkresults files, etc.) * Display time series t=[0,end] + Display time series t=[begin,end]: time bounds are not good for the second figure * Save figures as AVI movies: only available on Windows operating system * Popup menus and "Open file" dialog take a few seconds to appear on some XP systems == Figures issues (recordings / results) == * Stat: t-values cannot be displayed on 3D MRI slices * 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. * Channel selection on 2D Residuals : don't work properly for magnetometers only (indices issue) * MRI Viewer may not work well on MacOS * 2D/3D topography of modelized data (Fsynth) are always display with EEG colormap, even it is MEG . * 2D/3D topography of modelized data (Fsynth): does not work for multimodal reconstruction * Modelized data / Residuals: no sensors selection available * "Save image" may capture a blank image on Linux == Computation issues == * Tree menu "Project on default anatomy" : does not work for kernel / absolute values * Tree menu "Project on default anatomy" : does not work for kernels if there are some bad channels * Tree menu "Project on default anatomy" : cause Out of memory errors when processing FULL results (=> proceed by time blocks) * OS_MEG crashes Matlab when scalp in not very well aligned with sensors<
>Workaround: align your them well... * OS_MEG (overlapping spheres) fails when the scalp surface is not perfect (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
