I am new to freesurfer, and please forgive me if this is not the right way to present my issue.

I drew a ROI in QDEC, in the left hemisphere of a template and saved it as a Label file (a .txt file)

I would like to flip this ROI to the right hemisphere.

Does anybody know an easy way of doing it?

I tried manipulating the .txt file, but I could not do it.

Thanks in advance,

Raphael
