can you clarify what you mean? What 68 surfaces do you mean? And what do you mean by CNR of a surface? On Wed, 3 Apr 2019, neuroimage analyst wrote:

Hi, We were interested in measuring CNR of each of the 68 surfaces in Desikan-Killany atlas and compare between the groups to verify if our results are being biased by CNRs in the group?
I came across mri_cnr and mris_ms_surface_cnr binaries in the FreeSurfer tools and were wondering how to loop it through each subject in the subject_list.txt file (each column in subject_list.txt is the subject id) so that we get a text file (similar to ?cortical thickness txt file generated using aparcstats2table) that has # of subjects * # of regions txt file and the entries within each matrix cell is the CNR value corresponding to surface X of Subject Y.
We will greatly appreciate any help or pointers regarding this.
Thanks
Regards
