Hello list,
a few quick questions about the format of coords_for_fdt_matrix* and
fdt_matrix3.dot:
1) The file looks something like
57 69 27 0 1
57 70 27 0 2....
Are these the X/Y/Z coords of voxel number n, while n is in the 5th
column? Is the 4th column always 0?
2) is n the same number/reference which is in the 1st and 2nd column of
"fdt_matrix3.dot" (i.e. a unique voxel identifier)?
3) What are the origin and space of this coordinate system? Is it
diffusion space (same space as fdt_paths.nii.gz), and is the origin
(0,0,0) or (1,1,1)?
Thanks a lot,
Nicola
