BTW: You can't "sum" the thicknesses across the various regions in the
aparc files, as that would be a meaningless measure. You either need to
compute the average cortical thickness as I suggested, or compute a
weighted mean from the data in the aparc files, in which you weight each
region's thic
Yes, I think that using average cortical thickness is a reasonable
covariate to use in thickness analyses. And total cortical surface area
likewise if you are analyzing regional surface areas, although in the
case of surface area you need to decide whether to use areas based on
the GM or WM surfa
Hello, Freesurfer experts:
I found to report subcortical volumetric measure, ie, the volume of amygdale,
people tend to use icv as a control variable. Is there any corresponding
measure to correct the cortical thickness/area/volume results from autorecon3.
Because we have priori hypothesis of
