Hi Don, I found the problem (which is that it skips loading the target surface when the source and target subjects are the same; it now verifies that the ico order is also the same and loads the target surface if not). You can get the new version from here: ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surf2surf Alternatively, you can use the fsaverage3 and fsaverage4 average subjects ($FREESURFER_HOME/subjects) and skip the ico stuff all together (it should give identical results since the average subjects have the ico as their sphere.reg).
