Hi Douglas,
When I checked the summary created by FreeSurfer by running FS commands:
For cortical gyrification I get (here co-ordinates are in TalX TalY and TalZ):

Command to save these summaries were as following:
For gyrification: mri_surfcluster --in sig.mgh --subject fsaverage --hemi lh --surf white --annot aparc --thmin 1.3 --sum LH_Perform_LGI.summary1.3 For thickness: mri_glmfit-sim --glmdir xyz --cache 1.3 neg --cwp 0.05 --2spaces
Before these, I used general FS commands: mris_preproc, mri_surf2surf and mri_glmfit for both.
Only difference is I did not run mri_glmfit-sim on gyrification measures but ran this on thickness, area and volume measures due to orthogonal/non-orthogonal differences between gyrification and (thickness, area and volume) measures.
Thanks.

How do you know one is MNI and one it Tal? can you send a summary of your commands? On 8/4/17 2:09 PM, Martin Juneja wrote:Hi FreeSurfer experts, I am trying to correlate my behavioral data with whole brain cortical measures using cortical measures as IVs and behavioral data DV. Somehow the significant clusters I get from cortical thickness, area and volume are in MNI co-ordinates but significant clusters from local gyrification-behavioral data are in Talairach co-ordinates. I used identical procedures to preprocess my data but still I am getting my results in different co-ordinate systems (thickness, volume, area in MNI and gyrification in Tal). I would really appreciate any help.
