[IMP-users] Coarse Grain PDB structure

Hi IMP users,

I would like to know how to coarse a PDB structure using IMP, in a way to represent it as spheres but reducing the level of resolution (each 10 aa grouped and represented as a sphere).

I have tried reading the input PDB with IMP.atom.read_pdb to generate the atom hierarchy and with IMP.atom.setup_coarse_secondary_structure_residues, however without success.

Should I try using IMP.pmi instead?

Thanks!
