James, After indexing the images with LABELIT it is possible to write out an XPARM.XDS file that defines the unit cell, orientation, and beam parameters. For example, index an image first: labelit.index lysozyme_001.img --index_only This gives several possible Bravais lattice solutions...e.g. triclinic=1; tetragonal=9. Suppose you want XDS parameters for the tetragonal setting: labelit.xds_xparm 9 That outputs the XPARM.XDS file. I'd like to get any feedback from the community...this feature was added to Labelit in March 2011.
