Hi,
I would like to extract the 2D flat-map coordinates of cells that were
projected onto a 3D reference surface. Is there a way to save the 2D
coordinates directly from within Caret, or will I need to compute them using
the values in the cell projection file?
If I need to use the projection file, I found the file format listing in the
documentation (included below), but could you please explain what each entry
means (e.g. does cdistance(3) refer to a set of barycentric coordinates as
discussed in Drury et al. 1996; why are there three closest-tile-area values
for the inside projection; etc.)? Thanks,
