To get the same number of vertices, use --norevmap. I think it should
give them to you in the same order, but I can't guarantee it. Try it on 
a few vertices in isolation to verify.

Hi Guys,
I'm trying to map the vertices of temporal pole in one subject into 
the space of another subject using mri_label2label. When I do it, the 
output doesn't have the same number of vertices and the other of the 
vertex are completely messed up. See below as the first few lines in 
the source and transferred labels along with the command execution.
What I need to know is that where for example vertex number 129756 
mapped to in the target surface space. I can't extract those 
information from these two files.

Thanks a lot
