Hi Bruce,
For my 2nd point, I mean, after we get the lh.sphere.reg as the deformed
subject, it should have similar sulco-gyral pattern as the template. I want
to compute the distance between the deformed subject and the template, to
see how close they are after the registration. In other words, I
Hi Doug,
do you think it will be possible for you to fix that bug in a week or so?
It's somewhat crucial for my analysis.
Another thing I'd like to ask is: how feasible would it be to implement the
--min operation into mri_concat? There is already a --max to compute the max
of concatenated volume
Paula,
You must add at least two levels in each .levels file.
Ex: in the gender file:
*gender.**levels*
Female
Male

MC-Z will be independent of the number subjects. The z simulation
assumes an infinite DOF.

might be better to draw it on fsaverage and then propagate it to the
other subjects, but both would work.

Hi Tricia
did you check the tal xform? It is the basis of the ICV. If it looks good
then something else is wrong. If that's the case, upload the dataset and
we'll take a look

Hi,
I tried to use the white matter bug fix using v4.4.0 for data that was
originally run using v4.0.4. I then noticed that the IntraCranialVol measure
in wmparc.stats and aseg.stats for one of the subjects was -2083.23 (after
rerunning recon-all -segstats -wmparc). Is this due to the new way

Hi Stephan,
I guess you could draw the ROI in one subject at the appropriate tal
coords, use mri_label2label to map it across subject using the tal xform,
then sample it onto the surfaces of each subject.
cheers

We want to extract a spherical ROI of cortical thickness values
centered at the same Talairach coordinate for each brain in a study.
Any suggestions? In the 2007 archives there is an instructive thread

Hi Jidan,
we construct fsaverage by mapping the icosahedron vertices to a set of
subjects, then assigning that vertex to the position that is the average of
the tal coords of those vertices. Sorry, I don't understand the 2nd point.
Maybe you can explain what you are trying to accomplish?

Hi,
In the release notes for version 4.4.0 it says that "The -randomness flag
can be used to allow usage of a random seed", however, running the following
command:
recon-all -all -nowmsa -randomness -subjid f4168_1r
gives the following error:
ERROR: Flag -randomness unrecognized.
