Dear FreeSurfer experts,
in the publication 'Accurate and robust brain image alignment using
boundary-based registration', by Greve and Fischl (2009), in formula 2 a
quantity termed N occurs.
It is described as:'N is the total number of vertices participating'.
Can I find this N in the files
Dear FreeSurfer experts,
how can I increase the font size on the tkmedit scale bar?
Cheers

Hello Nick,
just installed and tested the BETA version.
In this case, you are just specifiying -per-session and not specifying
-mni305 or -surface
When you run mkanalysis-sess, specify -native instead of -mni305 or
-surface, like:
mkanalysis-sess -native -fwhm 5 ...

Hi Doug
format of the fmc files. Actually those files are
called fmcpr, if I use -per-run. How can do I have to proceed if there is more
than one run?

Hello,
I have two different results from a paired difference analysis lets call it A
and B. How can I do a two sample t-test with those results (A-B)? Somehow I am
stuck in using isxconcat-sess on the group results A and B. Help is highly
appreciated.
Cheers Joerg

I just noticed that the data I am currently working with are from a data set in
which the freesurfer protocol for the anatomical sequence has not been used.
Instead an in-house protocol is applied.

Dear Freesurfers,
I computed the functional activation in a sensory task using freesurfer's
fsfast stream. In the cortex surface line like activated regions are present.
Their extension is much larger than the extension of the expected regions.
Therefore, I suppose that those regions are due

Dear freesurfers,
I have a simple question concerning the freesurfer 5.1 FSFAST preprocessing. In
the preprocessing the functional images are registered to the anatomical ones
using bbregister. This is the 3rd in a series of 8 preprocessing steps. If the
preproc-sess registration fails it is

I want to segment anatomical data recorded from an experiemental sequence. This
