== Known bugs == ---- === Main window and database === * 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 * Load simultaneously datasets with slightly different sample rates: does not work === Figures issues (recordings / results) === * Stat: t-values cannot be displayed on 3D MRI slices * Figure menu "Set colormap max": does not work from the 3D figures with some versions of Matlab (eg. R2007a) * Cloned figures do not behave well <
>Example: Clone + scouts + moving in time : currents on cortex are not updated * Display topography + display channels from the tree : crashes if there are bad channels * Channel selection on 2D Residuals : don't work properly for magnetometers only (indices issue) === 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 * 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 * "Project on default anatomy" cause Out of memory errors when processing FULL results (=> proceed by time blocks) === Scientific issues === * Grand average computation does not weight the different subjects with the number of trials for each subject * Rounding errors with time values: sometimes there are +/- 1 samples selected than expected
