[Freesurfer] bug in surface-based area and volume

Hi Y'all, I recently found a bug in the way that FS converts surface-based area (eg, lh.area) and volume (eg, lh.volume) into standard space. I'm testing a fix now, but you should not use area or volume measures until I've posted the fix and you re-run either mris_preproc or qcache. The files themselves are fine, it is the way they are transfered to standard space that is the problem. You will not need to re-analyze any of your individual subject data. The volumes of the subcortical structures are unaffected by this problem. Global measures of cortical volume are also unaffected. I'll get back soon (next week) with the fix. Sorry for the inconvenience.
