Note that if you want to compute an average inside of a label, that you may want to use fMRI data that is unsmoothed (even on the surface) as this will cause false correlations between labels. doug On 01/21/2015 01:16 PM, Jan Willem Koten wrote: > Dear experts > I have created a larger number of labels on the FS_average surface and > performed an FS_FAST analysis.

[Freesurfer] Correspondence between label vertex number and time course
Dear experts I have created a larger number of labels on the FS_average surface and performed an FS_FAST analysis. The main goal is to obtain a functional connectome that contains all the possible correlations between 50 Rois in 100 subjects. The FS_fast analysis resulted in a 'fmcpr.sm5.subject.lh.nii.gz' file. I assume that this file has been mapped to the FS_average surface using spherical alignment. Therefore the vertex numbers reported in the FS_average label may directly correspond with the column position of the time course in the two dimensional lh.nii.gz for any given subject. Is this correct? Or do I need to transform the lh.nii.gz with a spherical coreg file? > > Thanks in advance > > Cheers Jan ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
