Hi - I would like to do group analysis on freesurfer data that is processed with verson 6. However when I try to run

recon-all -s subjid -qcache

I get following error after it runs for some time and generates some of the files.

ERROR: cannot find surf/lh.white.K

When I look at the log file - I see that this file was deleted. See following.

total integrated curvature = -1.022*4pi (-12.846) --> 2 handles

ICI = 169.4, FI = 1785.3, variation=28139.036

writing Gaussian curvature to ./lh.white.preaparc.K...done.

writing mean curvature to ./lh.white.preaparc.H...done.

rm -f lh.white.H

ln -s lh.white.preaparc.H lh.white.H

rm -f lh.white.K

ln -s lh.white.preaparc.K lh.white.K

Does anyone have any idea of what might be the issue here?

Thanks,

-Krishna
