Hi,

I have been getting a new error when using 'fast', FMRIB's automated segmentation tool. I can run 'fast -t2' on my T2-weighted images without errors (the result is expected segmentation of CSF, WM and GM). However, isolating the number of tissue classes using the command 'fast -c 2' inevitably results in an error, even when I run this command on data I have successfully segmented in the past.

Error reads:

[aura[129]:] (nmr-std-env) fast -c 2 temp

FAST - FMRIB's Automated Segmentation Tool Version 3.53

Image: /tmp/fsl_3bA3BQ_temp

AVWReader: Warning, /tmp/fsl_3bA3BQ_temp -- Can not read header file! Can not open file /tmp/fsl_3bA3BQ_temp.hdr!

If anyone is familiar with 'fast', any advice would be greatly appreciated. Thank you in advance.
