External Email - Use Caution

Hi Bruce and Vittal could be, but looks strange to me since the listed sulci seems quite consistant to me. Vittal could you put one of these subjets somewhere ; I could look at their cortical folding best

Hi Vittal

Christophe (ccd) can confirm, but I believe that there are areas in his parcellation that don't occur in every subject (rare folding variants).

Hello Freesurfer developers, I ran recon-all command to extract all subjects stats. Here I'm mainly targetting the surface area, volume, thickness and mean curve for all subjects. " recon-all -i /filepath/file/ -s /subjectid/ -all " this was the command i used. Now the problem is that I'm getting zeroes for the surface area which is parcellated from 'aparc.a2009s' and it occurred for a large number of subjects. The command for converting stats to .txt is given below: aparcstats2table --hemi lh --subjects 004 008 --parc aparc.a2009s --meas area --tablefile lh.a2009s. area.txt lh_G&S_frontomargin_area lh_G&S_occipital_inf_area lh_G&S_paracentral_area lh_G&S_subcentral_area lh_G&S_transv_frontopol_area lh_G&S_cingulAnt_area I wanted to know the reason for getting these zeroes. Could anyone plz help me out in this regard. Thanks in advance! Best Vittal
