Output and Input Tutorial


 After I had moved to the input_file directory following the Controlling Input and Output in Rosetta,I ran,

$ROSETTA3/bin/score_jd2.default.linuxgccrelease -in:file:s input_files/1qys.pdb

and I got the output,

-bash: /bin/score_jd2.default.linuxgccrelease: No such file or directory. 

What would you recommend doing?

Compiling Rosetta using



I downloaded Rosetta 3.12 linux + binaries and I noticed the the bin folder contained all 0 kb linuxgccrelease files. I have tried to compile Rosetta using the provided SCons version that was provided with Rosetta 3.12 linux + binaries download. I followed the "Compiling Rosetta" instructions from the user guide and executed the command 

$ python3 ./ -j 4 mode=release bin

Loop Modeling

I was getting an error while running the snugdock that I solved using the command. When I ran flags file using snugdock @flags file, another error came up saying "the antibody doesn't contain start or end of residue of cdr loop H1. Please check pdb is renumbered properly and passed -numbering scheme option matched the PDB.This could also mean missing density in the cdr loop. Loop modeling application can be used to fill missing residues."

protein binder interface design error


Hi! I ran into a problem when I was repeating the article "Design of protein binding proteins from target structure alone". The protocol I was followed is cao_2021_protocl_guide.txt. The step I was running is 12th: running a pilot job which is a protein interface design. could anyone help solve this problem?

Pepspec - sequence sampling



I am using Pepspec to optimize a 10mers peptide sequence to better binding to a membrane protein. In the design, I kept the first residue constant, while mutating the rest by all 20 amino acids. The flags file is the following:

-in:file:s ppk_complex_0001.pdb

-pepspec::pep_chain B
-pepspec::pep_anchor 1
-pepspec::n_append 9
-pepspec::n_peptides 10000
