You should check that anatomical analysis and make sure that it is correct. Once that is done, make sure that the subjectname in the subjectname file is correct, then preproc-sess should run. doug Michelle Umali wrote: > Hi Doug, > > I've run recon-all -all. I ended up inputing an .mgz file co

Re: [Freesurfer] Mapping segmentations to SPM Functional Space

2011-04-05 Thread Douglas Greve
There's nothing explicit, but it's not hard to do. You need to analyze your SPM data in the native functional space. Then register the functional to the anatomical using bbregister. Then map the segmentations into the functional space with mri_label2vol. doug On 4/5/11 3:04 PM, Palzes, Vanessa

[Freesurfer] Mapping segmentations to SPM Functional Space

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

Hi Michelle, the SUBJECTS_DIR is an environment variable that you have to set prior to running the anatomical analysis (disregarding the functional analysis for a moment). Before running the functional analysis, you must run recon-all on the anatomical data, eg recon-all -all -subject LD08-a

Hi Andrew, not sure if I understand. The surfaces in the longitudinal directories across time (within subject) are in registration, so you should be able to use the same annotation for all time points. Martin On Tue, 2011-04-05 at 11:20 -0400, Andrew Dumas wrote: > Hi FreeSurfer experts, > >

Make sure that your subjectname file has the name of the FreeSurfer subject folder as found in $SUBJECTS_DIR (it looks like it is empty). You don't need the retinotopy data in the $SUBJECTS_DIR. doug Michelle Umali wrote: > Dear Freesurfers, > I am still struggling with the retinotopy analysis.
