Hi there, I wonder if the fsgd file and the command lines listed below are corrected.
My sample included 4 groups with different diagnosis (g1, g2, g3, g4). I'm interested to map the vertices that show a relationship between the FC (obtained by FS-FAST) and cortical thickeness, regressing out the diagnosis. To this aim I used the --pvr option: mri_glmfit --y ces.nii.gz --wls cesvar.nii.gz --surface fsaverage rh --glmdir Thickness.wls --nii.gz --fsgd g4v1_thickness.fsgd --C intercept.mtx --C slope.mtx --pvr $SUBJECTS_DIR/rh.thickness.10B.mgh The fsgd file lists: ------------------------------------------------------------- GroupDescriptorFile 1 Title Relationship FC-thick reg out dignosis Class g1 Class g2 Class g3 Class g4 Input XX1 g1 Input XX2 g1 ... Input YY1 g2 Input XX2 g2 ... Input XY1 g3 Input XY2 g3 ... Input YX1 g4 Input YX2 g4 ... -------------------------------------------------------------- intercept.mtx 0.25 0.25 0.25 0.25 0 slope.mtx 0 0 0 0 1 thanks piero Piero Chiacchiaretta, PhD Institute for Advanced Biomedical Technologies - ITAB - University “G. d’Annunzio” of Chieti - Pescara Department of Neuroscience, Imaging and Clinical Sciences Via dei Vestini, 31 66013 Chieti, Italy tel: 39-0871-3556919 fax: 39-0871-3556930 e-mail: p.chiacchiare...@unich.it
