Version 1.5.1 of the OpenMMS software toolkit is now available on the OpenMMS website at
openmms.sdsc.edu. In addition to the fast database loader, this version contains all of the
pdbx fields from the PDB Exchange Dictionary (deposit.pdb.org/mmcif). This includes
attributes such as the model number in the atom_site record which is needed for NMR
structures. Also available in this release is the "xconv" program which converts mmCIF files
to XML files with the standard XML/PDB format.
