Known bugs


<<BR>>

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
