Hi Carolina You simply need to add the path ‘your FS installation dir/freesurfer/matlab’ to the search path in Octave: addpath(‘your FS installation dir/freesurfer/matlab’); For example, to build a histogram of cortical thickness values for the first subject of your study, you can try: thickness_data = squeeze(load_mgh(‘lh.thickness.mgh’)); hist(thickness_data(:,1)); where lh.thickness.mgh contains the thickness data for the left hemisphere of your subjects (eg.. those generated with mris_preproc) Cheers Jorge

Hi Jorge, Thanks for your reply, I installed Octave in the Ubuntu machine, Should I setup something in order to use the FS commands? Best regards, Carolina

Hi Carolina There is a directory freesurfer/matlab which contains several matlab-based scripts for reading and writing (after modified) surface- and volume-based data generated in freesurfer. Transport files from Linux to Windows will be tedious and things may not work properly, therefore, I recommend you to install Matlab for Linux or you can try with Octave (a kind of GNU Matlab for Linux). Cheers Jorge

Hello FS'users,
I'm trying to do an histogram of cortical thickness for 2 cases in matlab, but the problem is that I have Installed matlab in a computer (windows) and FS in another one (ubuntu) Can I configure something to use the FS commands in matlab in order to obtain some graphs? And also, where can I find the cortical thickness in each regions (Brodmann areas, gyrus or sulci) of the brain in order to compare a normal patient with a patiwnt who has a cortical dysplasia ?
Thanks a lot for your help,
Carolina
