Sorry for the follow up email, but I realized my mistake. When running the mri_robust_register command even though I used the lta flag for the output register file, I gave the extension .dat to the file. It seems like this is what caused the problem.

Dear FS community,

I used mri_robust_register to register a volume to the fsaverage space, and then tried to use the resulting .lta file to register another vol on the same space as the original volume, to fsaverage, using mri_vol2vol. The structure of the command I used is: mri_vol2vol --mov <file_to_move> --targ <fsaverage orig.mgz path> --lta ./<register_file>.lta --o <output_vol>

However, I keep getting the error: MatrixAsciiReadFrom: could not scanf parms

Do you happen to know what is the cause of that error?

Thanks in advance.
