Hi Scott, thanks for sending the data to test.
This ran fine on my linux box, but required 2.3GB ram to run, due to the
large number of time points and EVs. So it does seem that either you don't
have enough RAM+SWAP or disk space/quota, or more likely, that your linux
flavour has a 2GB limit on process size. Your local admin may be able to
tune your kernel to allow larger processes.

Other processes (MC, Melodic, and Registration) appear to have worked correctly. When I use the default FLOBS hrfbasisfns.txt file, thresholded activation maps are generated. I've changed the permissions on the hrfbasisfns.txt file so that they match those of the default FLOBS file (default had a+rw, the hrfbasisfn.txt I generated had a+r), and

However, after changing the output format to ANALYZE in fsl.csh,and processing the data again, I received the same error message (and again, everything worked well when the default FLOBS hrfbasisfns.txt was specified). In addition, the output files in the stats directory appear to be in nifti format (e.g., pe15.nii.gz)?
