[Camino-users] FA interpolation and coordinate system

[Yan Jin]

Hi,

I have a question about how to interpolate the FA value at a point on
a fiber. I noticed that in the current version of camino, the physical
coordinates of fibers refer to the CENTER of a voxel. So does that
mean if I convert them to the voxel space, let's say I get the voxel
index after conversion as (8.6, 9.2,3.5), should I add 0.5 on each and
make it (9.1, 9.7, 4.0) as the actual voxel index to do FA
interpolation at this point?

Also does camino provide FA interpolation point by point along the
fibers? tractstatimage only provides min, max, mean, etc., not
pointwise.

Thanks,
Yan
