Hi list,
I have some question regarding hippo-subfield parcellation.If I understand the
final results are thickness of each ROI but assuming a voxel of
0.5x0.5x0.5.Therefore, a correction is request.
A-How is the best way to do it?B-Correction for mean thickness or ICV is
advised? C-Is possible
Ciao Stefano,
- the output of this module is volumetric - there are therefore no vertices.
- You're right about the size of the voxels: they are .5x.5.x5, so if you
want a volume in cubic millimeters, you have to divide the volume in
voxels by 8.
- If you're performing a volumetric analysis of t
Hi Anastasia,
it worked perfectly and I could run probtrack between my anatomical seed
and using waypoints from Tracula tracts.
I have another doubt right now. The probabilities in each new tract are
very different. I divided every value with waytotal using fslmaths -div in
order to normalize them
I've attached a script that should do this. Let me know if this does not
work

That means I need to register the volume/s
Hi everyone,
In using Van Leemput's -hippo-subfields flag as part of the recon-all script to
obtain hippocampal subfield volumes, my lab has determined that larger
subfields are more relevant for our purposes clinically/surgically. Is there a
way to group the fimbria/CA1/2,3/4,DG/presubiculum/s
Dear Sierra,
there's no direct correspondence between these subfields and head /
body. If you want, you could create a geometric rule to subdivide the
hippocampus into head / body / tail, e.g., by creating a coordinate
system based on the major axis of the hippocampal shape.
Kind regards,
Eugenio
Howdy,
I'm trying to run *dt_recon* on some DTI data but seem to be having some
trouble with the number of b-values and b-vectors not matching the number
of data frames we have (see dt_recon logfile below).
Some basic parameters of our sequence are as follows:
- TR = 10 s
- TE = 96.2 ms
