[gmx-users] Chain length of a polymer

[Shan Jayasinghe]

Dear Gromacs Users,

I have a polymer molecule in my MD simulation and I want to calculate how
chain length varies with simulation time. How can I do that with Gromacs
software? Can I use gmx distance? Do I need to create a group with backbone
atoms of the polymer chain in the index file for the calculation?
Appreciate your help.

Thank you.
