Brian,

The DPS package uses the same indexing algorithm as MOSFLM, but has a
new refinement program which works differently and might do better in
your case. Version 2.0, including dps_refine, will be available on the
DPS Web site (http://www.chess.cornell.edu/MacCHESS/DPS) in about a
week. Right now, I would be very interested in trying DPS on your images
if you would like to send me a few.
