hello dear community,
I am simulating polysaccharides and I want to obtain their properties with the gromacs gmx polystat command, however I cannot obtain the persistence length and it is because I don’t know how to choose the atoms of a polysaccharide-type polymer. which atoms should i choose for this?

greetings

Hey,
you can try selecting the anomeric carbon atoms to define the polymer backbone.
