Hi, I afraid for very large molecules it may take a lot of memory. This is because internally the procedure generates and accumulates hundreds if not thousands maps.. You can try to make these maps smaller by changing resolution_factor=1./4 to resolution_factor=1./3 which may diminish the efficacy of the protocol but that's the only suggestion I have (apart from trying it on a "bigger" computer).

hi,

phenix version 1.11.1-2575

FEM has crashed a few times for me . i have tried using various parameters (resolution_factor=1./3, use_resolve=False) , but it will max out my RAM (24G) and get into swap space. It gets very memory intensive, i think thats why it crashed.

Do you have any suggestions to try ?

i previously had a similar problem with a pdb using conflicting chain assignments, but this pdb doesn't use chains
