So, after importing the 5FLM biological assembly 1 from the RCSB, I do the following:
Build->Build Mesostructure->Coarse Grain-> Run, it creates a reasonable structure with good connectivity, but it's in XSD format. When I try to export it to PDB or CIF, I generate an empty 1kb file. Is there something I'm missing? I'm just trying to convert the alpha carbons to CG particles and maintain the same residue to residue connectivity.
