Hi,
has anyone created functionality to compare the spatial correlation/similarity
of two patterns in the form of cortical surface overlays. What I am looking at
is a have
scalar at every point on the cortical surface. obviously this is just a list of
vertices with
a scalar value associated
Hi folks,
somebody stuck me with Ubuntu 16 for a month
and I found the perl problem and so switched to
the dev version which solved that problem.
discovered that with the dev version bbregister
throws an error having to do with fsl

I have R1 values that I want to resample onto the cortical surface. The R1
values were computed from a multi echo
T1 sequence that was also used to create the T1 weighted image that was used in
recon-all to produce the cortical surface reconstruction
probably measuring R2*, not R1.

(run mri_vol2vol with --help to get
more info).
btw, if you have multi echo data, you are probably measuring R2*, not R1.

hi folks,
when i run mri_glmfit-sim --glmdir rh.measure_t7cort.glmdir --cache 2.0 neg
i get an error message ERROR: cannot find

there is fsaverage... should i just make a soft link ?
also when i
Hi guys,
i am using the freesurfer-fsl integration to use labels from the freesurfer
cortical surface as seeds for probtrackx
probabilistic diffusion tractography. when the output of probtrackx is
generated it is already in the freesurfer
conformed space. I want to resample the output of probtr
I have probabilistic tractography output that is already in freesurfer
conformed space, i need to resample
it onto the cortical surface, how can I ?
i.e. mri_vol2surf does not have an option for the data already being in
registration ( requires transform.
i know i can load in freesurfer and sav
running mri_cvs_register --mov 004 --template 003

i saw martin kavec posted the same error but did not see a respon
can i get an update on the eta for the tracula associated tutorial data

i thought at one time i saw a paper on the tracula methods, maybe it was the
better tractography allignment paper.
is there a paper specifically about the global tractography method and related,
or an mit tech. report or anything
thanks

Hi,
I am using the cortical labels mapped into the aparc+aseg volume for seeding
qball imaging.
i looked around and did not find a complete listing of the numerical values of
all the cortical parcellation
labels.
I can of course load the aparc on the surface in tksurfer and map them to the
ap
Hi,
i want to extract epi time series on the surface, seems if i want every last
drop of accuracy from bbregister i will need to run
bbregister --mov epi_i_.nii --bold \
--s fbirn-anat-101.v4 \
--init-fsl --reg register_i_.dat
on every epi volume in the time series and then
mri_vol2surf
