Hi Derin,

there is a know and fixed bug in mris_calc in the 5.1 release. It has difficulties with very long file names and returns a non zero exit code, which stops my script in some situations.

I'll ask Nick if he can put up a fixed version of mris_calc for download.

Best, Martin

I received the follow error while running a set of subjects under 'long_mris_slopes,' and wasn't able to decipher the problem. It appears that mris_calc is not able to do the division for these files (dividing by 0 perhaps?). Any help appreciated, here's the command and tail end of output/error, thanks.
