Hello,
I am using mri_surf2surf and would like to use the vertex map method nnf
("neighest neighbor, forward only") which according to the --help description
exists and avoids multiple source vertices to be mapped and averaged onto a
single target vertex (crucial to my analysis here). However, when I run this
the output suggests that it is running the nnfr (neighest-neighbor forward and
reverse) method.
Is this a bug or am I misinterpreting the console output?
This is the command and output:
/usr/local/freesurfer/dev/bin/mri_surf2surf --srcsubject 994273 --sval
994273/Results/Orientations/lh_SSangle_depth00_rfMRI_REST1_LR.mgz --trgsubject
fsaverage --mapmethod nnf --o lh_SSangle_depth00_rfMRI_REST1_LR_inFSAv.mgz

I'd appreciate any suggestions.
