Dear Freesurfers, I would like to map my subject thickness data to the fsaverage subject, following ROI analyses, as described under step 4: http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness Before step 4, tksurfer showed me that registration from MNI to Freesurfer space of my ROI went well!
After that I would like to get thickness data using mri_segstats (step 5). However, Freesurfer indicates that the dimensions of my segmentation image (23406 x 1 x 7) are different from the dimensions of my input image (27307 x 1 x 6), and using mri_info suggests that sth seems to have gone wrong in step 4. I have searched in the Freesurfer archives and I understood that 23406 x 1 x 7 are the correct dimension values and followed the advise to use --reshape in the fourth step. This does however not change the dimensions (it still indicates in the Freesurfer output: Reshaping 6 (nvertices = 163842) which I guess should be Reshaping 7). Any suggestions to solve this problem of different dimensions are very much appreciated!
