This mask is from functional group analysis. Before I did do group analysis, I have to transfer all individual data into standard space. Therefore, there is no special reference for this mask. The only reference whole brain data is the standard talarich dataset in AFNI. I know if I want to get a pe

Dear FreeSurfer users, We wanted to make you aware of a paper recently published in Neuron by Makris et al. (Neuron, 2008, volume 60 issue 1 pp.174 - 188) that may prompt questions by reviewers of studies employing FreeSurfer. Please find attached the figure that the authors published in this pap

Thank you so much for your response, Nick! I uploaded "ROI5.nii" (i.e., abc.nii) just now. This ROI has been in Talarich space. Actually, it is from my group functional data. So I did not have corresponding T1-data. BTW: when can I read the web page describing the steps taken to get cortical t

Xiaochu, I'm putting together a web page describing the steps taken to get cortical thickness from an ROI defined by a volume mask. Can you send me these two files so that I can make sure the steps work correctly? 1) the ROI mask file (what you are calling 'abc.nii') 2) the T1-weighted anatomica

Hi Marieke, we compute the transform (12 parameter) to tal coords, but don't typically apply it, so you are correct, the T1.mgz is *not* in tal coords. From the subject's mri dir you can use mri_convert -at transforms/talairach.xfm T1.mgz T1.tal.mgz to transform the T1 into tal coords (and

Dear FreeSurfer people, I have got a very basic question. I would like to (or better: have to) do some manual tracing on my data. For this, I want my brains to be motion- and nu-corrected and in Talairach. Therefore, I apply the -autorecon1 step to my dataset. I always assumed that the T1.mg
