The resulting .ins file uses the new SHELXL facility to handle chain-IDs and automatically includes restraints for residues and ligands often encountered in macromolecular structures. In most cases the structure can tbe refined immediately with SHELXL without needing to change the .ins file from pdb2ins. pdb2ins is currently only available for 64bit operating systems. Because the file is rather large, it has to be downloaded sepately from the shelx download site.
