Quick mysql output question

Category: 
Scoring

Hello everyone,

I have compiled rosetta with OpenMPI and MySQL. It works.

I'm using relax to pack+score a few thousand poses but the output will create lots of tables with A LOT of info. I just need to output the pose name and the total score of the pose.

I was wondering which flags should I use (@relax.flags) to output only the SCORE table to MySQL, not the atom coordinates and the rest of the info.

By this I mean the same info as the default.sc file, but sent to a single table in mysql.

Thanks in advance.

Segfault when loading scorefxn() and load_from_pdb()

Category: 
Scoring
PyRosetta

Hi,

I am trying to load a structure from PDB and then calculate pairwise residue energies between residues in the structure. For this, I want to first load the scorefxn and then the structure (or viceversa), but whenever I try, either of them gives me a segfault, i.e. if I do scorefxn = get_fa_scorefxn(); pose_from_pdb() the latter crashes and if I do the opposite, get_fa_scorefxn() crashes.

Best Way to Append/Insert Residue

Category: 
PyRosetta

 

Hello everyone,

I am an undergraduate student researching with Pyrosetta for my lab this summer, and I am having difficulties appending/inserting residues into a pose. I would love some help.

I have tried using the grafting protocols (insert_pose_into_pose) but I just realized that there are methods such as append_polymer_residue_after_seqpos which seem to do what I want, perhaps more accurately.

Hello. I am wondering how many iterations is enough for remodel? Its a de-novo C-terminal extension: loop + helix of about 30 residues.

"Rosetta predictions of density, heat of vaporization (∆Hvap) and heat capacity (Cp(l))"

Scoring

In the supplementary material of the all-informative 2015 JChem paper The Rosetta All-Atom Energy Function for Macromolecular Modeling and Design  there is one detail that I do not understand and was curious about. Namely, "Rosetta predictions of density, heat of vaporization (∆Hvap) and heat capacity (Cp(l))".

Warning: Fold tree is not set properly for density scoring

Scoring

I am trying to build glycans into a cryoEM density following the Meiler Lab tutorial here: http://www.meilerlab.org/jobs/downloadfile/name/Apr2019_glycan_modeling_talk.pdf

 

Using the provided XML file, I am able to run the job, but I see the following warning throughout the output file:

0mcore.scoring.electron_density.FastDensEnergy: ^[[0m^[[1m[ WARNING ]^[[0m Fold tree is not set properly for density scoring!

Make fragments

Category: 
Docking

Hi Everyone 

I am currently working with the flexpepdock protocol and I need to create fragments. Unfortunately my peptides are short <27 aa and cannot use robetta. I am doing the fragment creation locally but the procedure is somewhat complex, could someone help me what steps should I follow to modify the make_fragments.pl script

Comparative modeling of metalloproteins

Structure prediction

Hi,

Hope everybody is doing well. 

I'm just getting used to using Rosetta and would appreciate some pointers with regards to comparative modeling of metalloproteins. 

I have a protein (155 amino acids) that binds to Zn. I know exactly which amino acids the zn atoms interacts with and I have 2 homologs for templates with homology in the 65% region. I've been reading this tutorial

manually defining CDRs in antibody modelling

Category: 
Structure prediction

Hi all,

I'm trying to use the antibody executable to create a model of an exisiting antibody. I have the CDR sequences that I need to model, so I created a fasta file and tried to run it. However, I get this error:

File: src/protocols/antibody/grafting/chothia_numberer.cc:149
ERROR: Unxpected length of h1 [length=3], length expected to be: [6, 7, 8, 9, 10, 11, 12, 13]!
