Hi Doug and Freesurfers,
I am using fcseedcor to compute the correlation between two time courses for
each subject in my group. The command that I run is as follows:
fcseedcor -s $subject -fsd resting -seed seed1.dat -seed seed2.dat -xreg
global.waveform.dat 1 -xreg vcsf.dat 5 -xreg wm.dat 5
Dear all,
I would like to use the fsfast functional connectivity pipeline to compute
connectivity between two binarized ROIs. One of the ROIs is a surface ROI, the
other is a hippocampal subfield. Based on the tutorial on

Dear freeview experts,
Is it possible to display multiple seeds (i.e., as a small circle) on freeview
surface view by specifying their coordinates? If there is no such feature,
could you suggest an alternative way to visualize seeds?
Thanks in advance!

Hello all,
How can I simply smooth a surface map (constructed using MRIwrite) using a
specific FWHM? mri_surf2surf requires source subject as an input but all I want
to do is to smooth a single group map.
Thanks in advance for your help!

Dear all,
We are modeling changes in cortical thickness over time using a cross-sectional
design. We have two groups of participants, age 8 to 18. In the cortical
regions that interest us, there is generally a linear decline in thickness with
age. Each group can be fitted to a best-fit
Hi Anastasia and FS experts,
I am trying to create a white matter ROI mask underneath a cortical ROI label
(e.g., 2 mm into the white matter) created in fsaverage space. I will then use
this mask to extract values from individual dtifit_FA and dtifit_MD maps
generated by trac-all. What would
Dear FreeSurfers,
I was wondering if there is a standardized way to construct a label that is the
complement of a regional label on freesurfer. For example, I have a customized
DLPFC label and would like to create another label that encompasses the entire
cortex except that DLPFC region.
Dear Doug/FreeSurfers,
We are looking at effects of age-squared on cortical thickness in two different
groups. We are interested in age-squared by group interactions on cortical
thickness across the surface. Nuisance covariates include age, sex, scanner,
and total brain volume.

Dear experts,
I am using aparcstats2table to extract values on a number of measures like
thickness, curvature, folding index, and surface area for specific ROIs. Is it
possible to create a table (using aparcstats2table) with all these measures
included or do I have to run it separately and

everything will be bogus). The y.mgh file
contains all the subjects in fsaverage space, so you don't need to run
it for each subject or resample back into native space

It looks like different runs have different number of slices. Is that right?
