Howdy-
I have a follow-up question. I'm going through the featquery shell script
and logs, and I'm not quite able to follow all parts. Specifically, I can't
tell where the value 24.2645433553 comes from in the following log line.
/opt/bliss/fsl/bin/fslmaths stats/cope1 -mul 24.2645433553 -div mean_func
cope1.feat/featquery/tmp
For the problem subject discussed below, the value is 4.91862312076e+16, and
this seems to be the source of the goofy percent signal change values.
However, I'm still unable to diagnose the root problem without knowing where
the value in question comes from. Can you point me in the right direction?
Thanks in advance,
Jim
