New to the list and just beginning with Python (Linux B console). Urgent
problem before I can correctly program:
How to insert "TER" records recursively, i.e. some thousand fold, in a file
like in the following example? "H2 WAT" is the only constant characteristic of
the line after which to insert "TER"; that distinguishes also for lines for
other atoms. Just to illustrate what I want to do - for those unfamiliar with
this type of file - a three-line set between two "TER" defines a water
molecule, with a set of xyz coordinates for each atom.
