I see,
Usually people look at thickness maps and volume on an ROI basis. Volume on the
surface I think is simply area times thickness. Not sure how meaningful that is
as area of a vertex depends on the triangle mesh.
Anyway, you look at smoothed maps on fsaverage. The average volume for each

Hi Martin,
I am running FS version 5.1.
This is the command line I ran:
long_mris_slopes --qdec ./qdec/long.qdec.table.dat --meas volume --hemi lh
--do-avg --do-rate --do-pc1 --do-spc --do-stack --do-label --time years
--qcache fsaverage
These are the outputs I get, which are located in the sub
In the files that you sent me earlier, the final bvecs had a set of 10
all-zero directions in the end (which I thought may have been caused by
the 10 empty lines at the end of your input Tbvecs.txt) Are those zeros
still there in bvecs?

Hi Vy, search for "coordinates" on our wiki. There are examples of these
types of transformations.

Dear Freesurfer Experts,
I would like to create ROIs for the MNI152 template using coordinates
obtained from our QDEC Monte Carlo Simulations results. However, the QDEC
results only list the Talairach Coordinates. Is there a program that I can
use to convert these tal coordinates to MNI152?
Thank
Hello again,
I have tried removing the empty lines and rerunning trac-all -prep,
but the error persists.

Hi Gabor - The info that tracula uses is which aparc+aseg labels each
pathway neighbors at each point along its trajectory. It learns this
information from the 33 subjects in the atlas, where the pathways were
labeled manually, and then applies that knowledge to reconstruct the
pathways in you
There are 10 empty lines at the end of your Tbvecs.txt file. Can you try
removing those and reruning?
Hope this helps,

hi Gari, looking at this I don't really see a problem. Yes, the t-test
is very significant, but I would expect that from a paired t looking
across different methods. the size of the effect is very small, about
1.5%. Do you see this as a problem?

Hmmm, that's a lot, but I'm very surprised that the final FWHM is over
30. How many subjects do you have? There might be one that is messed up.
You can check this by loading the y.mgh as a "time course" in tksurfer.
It will give you a graph with each subject. Finally, you can run

Hi Shannon,
that cannot be. It either indicates a serious bug (which we have not yet
encountered in our data) or a problem with your processing.
Can you send me:
- the version you use
- the command line you run
- the output you get
Also long_mris_slopes is designed for analyzing surface maps (an
Hi Doug,
For mri_glmfit I used a cortical thickness smoothed with a FWHM of 20,
resulting from using the -qcache option in recon-all.
