External Email - Use CautionDear FreeSurfer Developers, I downloaded the HCP_1200 subjects' structural extended data. I am attempting to have equal sized parcellation on scale 100, so I used parcellation results of Desikan atlas and increased the parcels from 68 to 100. after obtaining split file, I run the following commands on FreeSurfer: mris_divide_parcellation subj lh aparc.annot splitfile Desikan100 mris_divide_parcellation subj rh aparc.annot splitfile Desikan100 mri_aparc2aseg --s subj --annot Desikan100 --old-ribbon --o $SUBJECTS_DIR/subj/mri/Desikan100.subj.mgz The interesting part is that after running this command some disconnectivity were seen in the parcels as it is shown in the picture. In 3D view, also, when the parcels were loaded on dsi studio, there were some holes on the parcels which caused disconnected parcels. I will appreciate if you help me to solve this problem.
kind regards, Najme
