Dear Doug,
I want you could give me some guidances with my retinotopic analysis.
Eccen run: TR 2 Ncycles 6, 64 sec per cycle, all scan 384 sec.
Polar run: TR 2, then follow Ncycles 10, 32 sec per cycle, all scan 320 sec.
I write the rtopy.par:
stimtype polar
diretion neg

and

Here's part 1. I'll write until I have to catch my shuttle, answer the
rest tomorrow ...

Apologies for my previous long email; if anyone gets a chance to look over
the questions I'd be really grateful!
Many thanks indeed,

I agree with Bruce. You can use MRIread.m to read in the data.
Regarding the other question: first you need to combine the posteriors
of all the subfields into a single posterior for the whole hippocampus.
You can do that like this:
mri_concat posterior_fimbria.mgz posterior_CA1.mgz ... --sum --o
Hi Marcos
I would do it in matlab. Compute the spatial eigenvectors then divide the
hippocampus up along the primary eigenvector

Thank you for your answer, Juan.
Yes, I want a surface of the whole hippocampus and I thought I had just
obtained that using freeview and adding all hippo-subfield files. That
resulted in the screenshot I previously attached. I just do not know how I
can save the resultant surface.
After I check
Hi Claudia
that defect is bigger than more cortical surfaces so something is
dramatically wrong. Did you check any of the outputs (wm.mgz, filled.mgz,
lh.orig, etc...)?
cheers

Hi Anupa
you need to specify each input volume with -i if there are more than one.
In your example you would need an inner loop of the form
set inputs = ()
foreach vol (SZ*.nii)
set input = ($inputs -i $vol)
end
recon-all $inputs ...

Hi everyone,
I would just say you thank you for the help you give to Freesurfer users. I use

Hi,
Sorry for the answer too late.
I tried the command to evaluate the RMS distance but I just get the difference
between the 2 surfaces in terms of faces and vertices.
But I would compare my 2 surfaces by calculating the euler characteristic (
vertices-edges+ faces) .
Thank you so much for
Dear Freesurfers,
After running the first tests of freesurfer 5.2, I found a file named
$hemi.w-g.pct.stats on the stats folder. The last column of the file is a
SNR calculation, i found on the help manual, that is required to add --snr
to perform this calculation.
I'm interested to know how this
Hello,
I have troubles with saving my files, after I did some segmentation
changes. I think this could be related to a problem, which I have,
when I load the brainmask:
libGL error: failed to load driver: nouveau
libGL error: Try again with LIBGL_DEBUG=verbose for more details.

I went thru the link suggested by Mr.

I already created a DLPFC for one individual.
I want to know how to measure the corti
