We need to write python or perl script that will generate a CLUSTER file for fragment analysis.
Building on what we already have, we could use the memebership files that we already use for DOS calculations in donor-acceptor systems.
These membership files are tied to the XMOL.DAT file for the complete structure. So, we can use them to create a CLUSTER file that will list the atoms according to the memebership files.
Any volunteers? I will offer you a glass of water if you do it.
