Hi Greg,
Thanks for your note. I actually got rid of the perl script already so in 5.1 it should not be a problem any more.

if you cut and paste this in your freesurfer SUBJECTS_DIR it runs fine
but executing strace -f -o /scratch/trace.foo mri_cvs_register --mov 004 --template 003 --step2
one of the output lines is 16837 open("iteration.node", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 EROFS (Read-only file system)
on another computer where i have freesurfer installed in my home directory the program runs fine.
so it seems that when the perl script executes the command and freesurfer is installed in a system directory like /usr/bin/... that the perl script home dir at the point of the system call is in the system directory and it is trying to write there rather than somewhere in SUBJECTS_DIR or other user writable location and surf2vol fails when it tries to open a file in write mode in a system directory
