NBRF/PIR Format:
A sequence in PIR format consists of:
1. One line starting with
1. a ** (greater-than) sign, followed by
2. a two-letter code describing the sequence type (P1, F1, DL, DC, RL,
RC, or XX), followed by
3. a semicolon, followed by
4. the sequence
I know, in PyMOL using 'symexp' possible to generate symmetry related
molecules for a given crystal structure. But I'm looking for some
program/software (for batch) by which I can find out the number
of symmetry related molecules (distance cutoff = 5A) interacting with
a given chain in a crystal
