# Scoring

## Explicit water

Category:
Scoring

Hello,

I have a pdb with crystallographic waters which appear to be important for the protein structure, and perhaps function. I am generating mutations using pyrosetta and evaluting their relative scores, and exporting structures to be simulated with MD.

## Less silly way to get number of iterations of Relax

Category:
Scoring

Currently to get the number of iterations a mover, such as FastRelax does, I enable the dump_trajectory scoretype and count the models in the PDBs (code below).

This seems very very weird way of doing this, so I was wondering if there is a less silly way of doing this?

Also, is there a direct way to open a multimodel file say to get the scores of each? (Rather than extracting the models, writing to file, reading them into PyRosetta and scoring them).

## Scoring in Rosetta

Category:
Scoring

Hey all! I am quite new to Rosetta so I am hoping someone may be able to help. I understand how scoring works in Rosetta and how it is calculated but what I do not know is what a 'good' score is. I am trying to minimize a decently large protein and I don't know what sort of score I should be looking for. Thanks!

## Why does the sum of the per-residue total energy not match the whole score?

Category:
Scoring

At the bottom of a scored PDB file is a POSE_ENERGIES_TABLE. The sum of total, which is already a dot product with the weights, does not match the total score.

Here is an example in Python3, either with or without PyRosetta —This is a question about the C++ not the Python bindinds, hence my posting in Rosetta General

## Differences between energy values reported in the tutorials and the ones obtained by running the code, what is normal?

Category:
Scoring

Hello, I am new to using Rosetta so appologies for the very basic question

I work with Rosetta version 3.12 and I am following the tutorials: https://www.rosettacommons.org/demos/latest/Home

When I run the examples from the tutorials, the energy values I obtain are significantly different from the results of the tutorial.

## Hydrogen Bonding Distances and Atom identification

Category:
Scoring

We are using PyRosetta 2.83 to identify hydrogen bonds between atoms.  For example, take the following code:

pose = pose_from_pdb("/Users/kmolloy/Downloads/2ezk.pdb")
hbond_set = pose.get_hbonds()
hbond_set.show(pose, 5)
hbond_set.show(pose,7)

This results of running this code are shown below:

## Error using ddg_monomer application (Assertion pose.residue(resnum).name1() == wt failed)

Category:
Scoring

Hi, I've unsuccessfully tried to run ddg_monomer app. I want to study the estability of a small protein after some mutations. I have used a pre-minimized pdb file as an input file, but I have the following error (last lines):

apps.public.ddg.ddg_monomer: wt is N resnum is 25 and mut is P
apps.public.ddg.ddg_monomer: wt is Y resnum is 60 and mut is H
