Hi,

I am attempting to move an annotation file from the right to left hemisphere. I have run xhemi registration with:

surfreg —s $subj —t fsaverage_sym —lhrh
surfreg —s $subj —t fsaverage_sym —lhrh —xhemi

The annotation file is rh.myclusters.annot in the $subj/xhemi/label subdirectory. I've tried using both mri_surf2surf and mris_apply_reg:

mri_surf2surf --srcsubject s1315_base/xhemi --sval-annot $SUBJECTS_DIR/s1315_base/xhemi/label/rh.myclusters.annot --tval $SUBJECTS_DIR/s1315_base/label/lh.myclusters.annot --trgsubject s1315_base --srchemi rh --trghemi lh --srcsurfreg fsaverage_sym.sphere.reg --trgsurfreg fsaverage_sym.sphere.reg

mris_apply_reg --src-annot $SUBJECTS_DIR/s1315_base/xhemi/label/rh.myclusters.annot --trg $SUBJECTS_DIR/s1315_base/label/lh.myclusters.annot --streg $SUBJECTS_DIR/s1315_base/xhemi/surf/rh.fsaverage_sym.sphere.reg $SUBJECTS_DIR/s1315_base/surf/lh.fsaverage_sym.sphere.reg --no-rev

I've tried mris_apply_reg with and without the '--no-rev' flag. The output from each of these commands is the same: the clusters are on the medial aspect of the LH. They were clusters in the supramarginal and temporal regions on the RH, so I was expecting them to be in the same regions on the LH.

Thanks,

Peggy
