you can try doing the same thing using the -per-session flag. The
problem is that it tries to use the motion correction to correct across
sessions, which may or may not work

I want to do the analysis in native space. I saw in a past thread that the
native space analysis cannot make use of the -per-run flag. Does this still
hold?
If so, is there another way to get fsig.nii file after analyzing each
session separately in native space?
Thanks for your help!

To get the F test, you will need to put the runs from both sessions in
the same bold folder (and make sure to use -per-run registration)

Thanks for your help Doug. That cleared things up.
One more question, I want to average over 2 of these scan sessions for the
same subject. Is there a command or option that will let me do this and
output the fsig.nii file for the average activity?

sorry, there should be an fsig.nii.gz which is the F test of the real
and imaginary. That sounds like what you are asking for

To clarify, I am piggy-backing on the retinotopic analysis to map out
orientation preference with the travelling-wave method. We presented
subjects with a rotating grating and right now I am simply interested in
finding the voxels that have significant activity in response to any
orientation. Now,
They are compared against 0 (ie, no change from baseline). The negatives
just mean that the real component was negative

So I want to figure out which voxels were modulated significantly by the
orientation of our stimuli. Is this the right file to look at? If so what
are the real and imaginary components compared against? I want to know to
make sense of the negative values.

It is the -log10(pvalue) where pvalue is the p-value from the F-test
of the real and imaginary components

Hi freesurfers,
I conducted a retinotopic analysis for one of my subjects. I was wondering
if any of you knew what is represented by the values in the sig.nii file
under the 'polar' directory that the process puts out.
I appreciate your help!
