I have only been working with IDL for a few weeks and have run into a
problem I could use some help on. We are trying to get different cross
sections from a volume, and would like to be able to specify our slicing
plane with Miller indices. I was wondering if there is a function similar
to extract_slice that we could use to do this, or if anyone knows where I
could find some code that would convert our input into the proper form and
call extract_slice internally.
Thank You,

What I vaguely remember from a solid state physics course long ago is that
the Miller indices of a plane, for all but non-cubic lattices, are just
vector coefficients of the normal to the plane. So couldn't the Miller
indices be input directly into the PlaneNormal argument of EXTRACT_SLICE? I
haven't tried, but it would seem that the other input needed is Xvec,
indicating something like the X direction of the plane grid, I think.
I'm no expert at all, but the thread seemed so silent...
