Hi Ali,
not sure if your email was garbled or you are using the wrong command line. The option to tksurfer should be -overlay-reg <register file name> not ?ovreg. If you tried it with -overlay-reg can you send us the output?
cheers Bruce

Hi, I'm trying to use a registration file while overlaying my functional volume on the surface. I'm getting this warning

I also tried with -overlay-reg flag but got the same warning. The results are the same with or without the registration file, so I'm sure that I'm failing to load it. Loading the registration.dat from gui menus also doesn't make a difference visually.
Does this indicate that my registration.dat file is bad or am I making an error in the tksurfer call? Any help would be appreciated. Regards, Ali Arslan
