I found a couple older threads about creating a probabilistic mask in Freesurfer: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg11790.html https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2010-July/014953. html I have modified mri_ca_label with the flag -write-probs and inste

2012-02-27 Thread Palzes, Vanessa
Could someone please explain to me the difference between mri_binarize and mri_extract_label? I had been using mri_extract_label to create ROI masks of cerebral white matter (2 and 41). I recently became aware that this would give me a label with 0 and 128. I tried mri_binarize (with the same matc

Hello, I am continuously getting a "Segmentation fault" error during -autorecon1 when it's running mri_binarize. I have been running Freesurfer on a Mac, but now I am trying to implement it using Linux. I am running this version: freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 on Linux 2.6.9-

[Freesurfer] Mapping segmentations to SPM Functional Space

2011-04-05 Thread Palzes, Vanessa
I am wondering if there is a similar function as aseg2feat (which maps the automatic segmentations from Freesurfer to FSL FEAT functional space) for the use in SPM functional analysis. This tool poses to be very useful in creating ROI masks, however, we are using SPM for functional analysis rather

[Freesurfer] ROI mask

2011-01-27 Thread Palzes, Vanessa
Hi all, I am currently exploring anatomical ROI analysis in FreeSurfer. I would like to create ROIs based on a Brodmann Area atlas, since unfortunately FreeSurfer currently only segments a few of these regions automatically. I know I could define the ROI manually in FreeSurfer, but I would pref
