multiple recon-all processes
by Ahmed, F, Me <fahmed＠sun.ac.za> 05 Nov '09

05 Nov '09

Hello, I know that FS can run multiple recon-all processes at one time, but I wanted to know how exactly one can do that. Is it just a matter of opening a terminal window for each recon-all process you wish to run? Thanks, Fatima

RES: Single subject vs. group
by Pedro Paulo de Magalhaes Oliveira Jr 05 Nov '09

05 Nov '09

Our group published a paper with single subject vs group. The paper you can find in FreeSurfer's website article list: search by polymicrogiria If you want to discuss the results we published send me an e-mail. -----Msg original----- De: Tricia Merkley Enviado: 05/11/2009 00:15:17 Para: freesurfer(a)nmr.mgh.harvard.edu Assunto: [Freesurfer] Single subject vs. group Hi, I've seen similar questions posted to the list, but I haven't been able to find an answer. So sorry if this is a repeat. Is it possible (or even advisable) to create a map comparing cortical thickness for a single subject against a group? If so, how is the best way to go about doing that? Would I need to use z-score transformations? I would appreciate any suggestions for this. Thanks, Tricia Merkley

Skull Stripping Free surfer
by Ribes Delphine 04 Nov '09

04 Nov '09

Dear Users, I've just started using FreeSurfer. I would like to use it for skull-stripping. I've created a batch file to process all my subjects. and I am basically using the command line: recon-all -autorecon1 -skullstrip -s subj1 I would like to know if there is a way to only do skull-stripping and not doing the Talairach Transform and then INU correction? I would like to have the skulll-stripp volume in the same space coordinate as originally? Otherwise, I am doing skull-stripping of T1 weighted images of normal elderly subejcts. Is there any specific recommandation for skull-stripping parameters? Thanks a lot, Delphine
