Unsolved

I have a question regarding Pyrosetta. Currently, I want to use pyrosetta to score some protein structures but with missing atoms in sidechain. So my protein structures contrain full-atoms for backbone but missing one or two atoms per residue on sidechain. I used pose_from_pdb to read my protein structure (pdb). But it seems pysoretta will fill in the missing atoms according to rotamer library. Is there a way to prevent it so I can just score my structures with missing atoms on sidechains?  

Thanks a lot for the help,

A pose can have a constraint set, a modifiable residue set, an unnoticed `pose.pdb_info().obsolete() == True` case, virtual residues, energies and a few more. Therefore when saving to disk none of the following truly work as they save coordinates:

pose.dump_pdb('foo.pdb')
pose.dump_scored_pdb('foo.pdb', pyrosetta.get_fa_scorefxn())
pose.dump_cif('foo.cif')
pose.dump_mmtf('foo.mmtf')
pyrosetta.io.poses_to_silent([pose], 'foo.silent')

So I was hoping for an all-in-one

The above tells me that an RNA low-resolution potential

(rna_lowres_sf = core.scoring.ScoreFunctionFactory.create_score_function("rna/denovo/rna_lores_with_rnp_aug.wts"))

I am trying to use the makefragments.pl to get a sequence profile for 1203 residue monomer of the sars-cov-2 spike protein and Ive run into a error about SS0 predictor. Im using this command line

make_fragments.pl -verbose -psipredfile ab42c8a0-7d52-11eb-a871-00163e100d53.ss2 -n_frags 200 -n_candidates 200 -frag_sizes 3,9 sequence.fasta

I was wondering what things would make the predictor nonfunctional and if there is a physical file that I could interact with. Or if the predictor relies on files from the nr database.
