Hi - I have a few questions about WB functionality and plans for
functionality
a) what is the position on flatmaps? can these be displayed (e.g. made in
CARET5, saved as "surf.gii", will they work? what if the flat coord file
has fewer nodes than the original mesh, which is fine in caret5)
b) there's a nice facility to specify a distance from the white or pial
surface and make an average "laminar approximate" surface at that distance.
but laminae vary in thickness. If one specified multiple distances from the
WM at different points on the mesh (with ROIs and e.g. a spline) it could
be possible to more accurately follow actual laminar lines in high
resolution MRI. I guess that is more of a thought than a question. It would
be really useful.
c) most importantly: given an FSL BEDPOSTX model, one can "estimate fiber
binghams" and also "Takes precomputed bingham parameters from volume files
and converts them
to the format workbench uses for display."
in either case: how does one actually do that? what does the display look
like?
there is -cifti-create-label and -cifti-convert
if one has a GM/WM segmentation, made by e.g. FAST, how can one generate a
suitable cifti from it to pass to "-estimate-fiber-binghams?
and does it actually matter to -estimate-fiber-binghams what the labels (WM
or GM) are? does it treat GM labelled regions somehow differently?
I probably don't want to do that (treat them differently in any way).
It would certainly be nice to display mean fibre orientations as little
vetors like caret_command -map-fsl etc
But it seems like there more to this. I can't quite get a grasp on it. I'd
like to have a look.
The latest stuff is great. Thanks. especially applying flirt transforms to
surfs that's really wonderful.
best,
Colin
