Hello,
I'm relatively new to GROMACS, and I need to write some of my own analysis
tools using the template.c file.
I have been able to figure out most of the structure of it, and how the C
Structs are used. That is to say, I can successfully retrieve particle
positions, residue IDs, residue names, etc.
The one piece of information that I can't seem to be able to retrieve is
bonding information. Is there a way for me to get this? I should mention
that I run the program by inputting a traj.trr and topol.tpr files, so I
have access to the information saved in those files.
The easiest way to learn how to use the information in the .tpr is to
work by analogy from an existing tool that has to parse the bonding
information, preferably in a similar way. I just can't think of one that
really looks at the bonding topology, rather than using a set of atoms
belonging to a group, residue or molecule.
Why do you want the bonding information? Maybe you don't need it...
