age/ contains

SUBJECTS_DIR has average directory with the group av surf & vol stuff

I run

mri_surfcluster --src lh.sickle.glmdir/age/sig.mgh --sum lh.sickle.glmdir/age/sig.cluster.sum --ocp lh.sickle.glmdir/age/ sig.cluster.mgh ( on same line of course ) and get ERROR: hemi must be supplied I add --hemi lh and get ERROR: srcsubjid must be supplied etc. can't seem to make it happy.

thanks
