[Freesurfer] transferring annotation from one subject to another

Hi all,

I have an annotation for fsaverage that I would like to convert into a subject's space.

Up to now, the only way I found to do that was to convert my annotation to all its labels, and then rebuilt the annotation in the subject's space from the labels, using the following 3 steps

mri_annotation2label --annotation myAparc --hemi ?h --subject fsaverage --outdir fsaverage/label/ mri_label2label --srcsubject fsaverage --srclabel fsaverage/label/?h.label1.label --trgsubject SUBJ --regmethod surface --hemi ?h --trglabel SUBJ/label/?h.label1.label (which needs to be repeated for each label) mris_label2annot --ctab myColorLUT.txt --l ?h.label1.label [ … up to --?h.labelX.label] --s SUBJ --a myAparc --hemi ?h

That is however not really efficient for annotations including increasing numbers of labels. Is there any other way to convert more efficiently the annotation, something like an annotation2annotation command?

Thanks a lot in advance for your answer,

Marie
