Patterns can be combined into comma separated lists such as "trp,phe,tyr" meaning TRP or PHE or TYR.

Patterns that are sepatated by blanks must all be true such as "chainb 1-5" meaning residues 1 to 5 in chain B.

You can also group patterns with parenthesis, separate multiple patterns with | meaning ’or’ and choose the complement with NOT as in "not file1" meaning not in file 1.

An autobondrot file is similar to other PDB input files but it includes information identifying atoms subject to rotations and other transformations.

Example autobondrot file fragment showing Calpha-Cbeta bond rotation and a periodic torsion penalty function for this rotation
