hi q. from a collaborator, someone got a comment for 1 subject the # of vertices of sphere file different from the length of thickness data for the same subject.

Subject: Re: Help Deepti with some questions Dear Greg I have been looking at FreeSurfer data provided by you for 21 subjects(AD/Control). For P1_AD subject I found the # of vertices of sphere file different from the length of thickness data for the same subject. # of vertices for P1.AD subject are 131364 and length of thickness data for the same subject is 131215. However for rest 20 subjects # of vertices and length of thickness data are same. I am using MATLAB to read thickness.asc data and last column is thickness (mm) at given x,y,z. For vertices and faces I am using the standard freesurfer_read_surf.m form http://eeg.sourceforge.net/doc_m2html/bioelectromagnetism/freesurfer_read_surf.html I am just wondering how to fix this discrepancy of freesurfer output? Also thickness data P10 is missing in asc folder. Sphere and pial files are present in surf folder for P10 subject.
