Dear Freesurfer Experts,

after a new installation of freesurfer, the command "tkmedit" worked, but with the command "recon-all -i ... -s ..." we ran into the following error:

recon-all exited with ERRORS at Thu Jan 21 08:17:06 CET 2010

Any suggestions, what the problem might be?

Best regards and thanks in advance
