Hi,

I'm running the NIAK preprocessing pipeline (niak-0.6.4.1) on a Linux machine at the BIC. t1_preprocess keeps failing at the Non-Uniformity correction step, I've attached the log-file below. I have tried to run 'nu_correct' from a Terminal with the same inputs and it works perfecly fine from there.
Any ideas?

Thanks a lot,
Peter
