Developers,<div><br></div><div>I am doing some automated analysis on many pdbs. My analysis is contained to a single chain in a given pdb. Aa such, to cut down on computing time I am generating many pdbs cut to the desired chain. When using pdbtools I get the following</div>

<div><br></div><div><div>Sorry: Fatal problems interpreting PDB file:</div><div>  Number of atoms with unknown nonbonded energy type symbols: 46</div><div>    Please edit the PDB file to resolve the problems and/or supply a</div>

<div>    CIF file with matching restraint definitions, along with</div><div>    apply_cif_modification and apply_cif_link parameter definitions</div><div>    if necessary.</div><div>    Also note that phenix.ready_set and phenix.elbow are available</div>

<div>    for creating restraint definitions (CIF files).</div></div><div><br></div><div><br></div><div>Is there a way around this without creating a CIF file or another tool to cut pdbs?</div><div><br></div><div>Thanks,</div>
