I'm trying to use FSL on data that I collected using GE's EPIBOLD sequence,
and reconstructed using their EPIRECON program. I modified a program to
convert the GE format into the .img (and .hdr) files and believe that it is
working correctly. When I run FSL, things go ok until I get the following
(I included a couple of commands that run fine to help demonstrate where I
am in the process):
---------------------------------------------------------------------------

Once I get to this point, the program stops. I'm not sure why? Got any
advice?
