If there are negative values in the lh.area, then something is very wrong. Can you double check? If they persist, can you upload the subject? doug

after recon-all i ran recon-all -s $subject -qcache

this generates lh.area.fsaverage.mgh which only contains values 0 and higher while negative values exist for the lh.area of the same subject.

is this normal and if so, why?

thanks, -joost
