Subject: superpose atom selection
To: CCP4BB@jiscmail.ac.uk
Hello all,
from the ccp4 manual:
http://www.ccp4.ac.uk/html/superpose.html
snip
superpose foo_1st.pdb [-s CID1] foo_2nd.pdb [-s CID2] [ foo_out.pdb ]
where [-s CID1/2] are optional selection strings in MMDB convention,
and [foo_out.pdb] is optional output file.
/snip
Please, could someone point me to documentation of said MMDB convention.
Many thanks in advance,
Wolfram Tempel
