IDXREF

  1. reads a list of spot positions from SPOT.XDS and converts them to vectors in reciprocal space
  2. calculates primitive unit cell parameters from the (clustered) difference vectors
  3. as a control, prints out indices (which should be close to integer numbers) corresponding to difference vectors
  4. uses the cell thus obtained to evaluate possible alternative origins of reciprocal space close to the one that is calculated from ORGX ORGY
  5. evaluates all possible Bravais lattices corresponding to the primitive unit cell (and gives the unit cell parameters and reindexing transformation for that lattice)
  6. refines the geometry describing the diffraction experiment and writes the result to XPARM.XDS
