[Freesurfer] MNI/Startup.PM error in FreeSurfer 4.4.0

Hello. I just installed FreeSurfer v4.4.0, following all the directions to the letter. When I run recon-all -i -s -autorecon1, I get the following error: Can't locate MNI/Startup.pm in @INC (@INC contains: /System/Library/Perl/5.8.6/darwin-thread-multi-2level /System/Library/Perl/5.8.6 /Librar

Re: [Freesurfer] freesurfer dice coefficient calculation

Hi Jared, yes, the talairach.m3z is the intersubject registration we use for generating the aseg, and you could use it to compute a dice. cheers Bruce On Tue, 30 Jun 2009, Jared Price wrote: Hi freesurfer masters, Quick question on the way freesurfer calculates the dice coefficient. I am

Hi, I ran the following preproc-sess command and mkbrainmask-sess failed, with an error message of not finding fsmaths. I don't know where to be looking for this file and what previous command should have generated it. Can anyone help me out? Thanks! Dahlia. I ran: preproc-sess -sf sessid_subj31

[Freesurfer] freesurfer dice coefficient calculation

Hi freesurfer masters, Quick question on the way freesurfer calculates the dice coefficient. I am interested in getting an INTERsubject dice coefficient as a measure of similarity between 2 subjects. My question is, do I need to do an INTERsubject registration step before calculating the dice

Re: [Freesurfer] mri_surf2surf

Hi Jidan, The surface in the native space is given by ?h.white. ?h.sphere and ?h.sphere.reg provide the "mapping" of those vertices of to a spherical representation, and registered spherical representation, respectively. There are ways to get at the Jacobian of these transformations if that is w

Re: [Freesurfer] image matrix

Hi Feng-Xian, the surfaces all live in the surf subdirectory. To see how many vertices a surface contains you can run either mris_euler_numer of mris_info. The thickness is in the ?h.thickness ("curv" format file - one scalar per vertex) and the inflated is in ?h.inflated surface format. You c
