Dear Bruce, Thank you for your answer!
I just display the "T1.mgz" image (mri folder) using Freeview and then loaded the "lh/rh.perirhinal_exvivo.label" rois (label folder). If this is not the good way to do it, please, could you explain more the procedure? What do you mean by MT and PC? Thank you very much in advance, Best regards, Mohamed ----- Mail original ----- De: "Bruce Fischl" <fis...@nmr.mgh.harvard.edu> À: "Freesurfer support list" <freesurfer@nmr.mgh.harvard.edu> Envoyé: Vendredi 19 Janvier 2018 16:53:18 Objet: Re: [Freesurfer] freesurfer segmentation: perirhinal Roi Hi Mohamed how are you visualizing the MT or PC ROIs. Did you sample them into the volume? If so, can you tell me where the file ROIs are in the data you sent me? cheers Bruce On Fri, 19 Jan 2018, m.ba...@uliege.be wrote: > Dear Bruce, > > Many thanks for your kind help! > > I put the subject data on your ftp site (s8201.tar). > > Best regards, > > Mohamed > > > > ----- Mail original ----- > De: "Bruce Fischl" <fis...@nmr.mgh.harvard.edu> > À: "Freesurfer support list" <freesurfer@nmr.mgh.harvard.edu> > Envoyé: Jeudi 18 Janvier 2018 16:37:10 > Objet: Re: [Freesurfer] freesurfer segmentation: perirhinal Roi > > Hi Mohamed > > if you tar, gzip and ftp this subject to our ftp site we will take a look > cheers > Bruce > On > Thu, 18 Jan 2018, m.ba...@uliege.be wrote: > >> Dear Bruce, >> >> Attached is the screen shot of the results of the segmentation of the >> perirhinal Roi with Freesurfer V6.
