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:

I'd appreciate any suggestions.
