External Email - Use Caution Dear experts, I would like to show the across-subject overlap of voxels by creating a map with color coding indicating the number of subjects activating corresponding voxels. For each subject I have run the first level model in spss and saved the 1000

Dear Freesurfer users, I would like to perform surface based fMRI gorup analysis in Freesurfer starting from SPM first level output files, but I am not succeding. I have already preprocessed the data in spm and used Freesurfer for boundary based registration, I have succesfully ran the recon -all
