Hi,
I have a couple of questions regarding Rosetta clustering and Calibur and I wasn't able to find an answer to them on the site
Which type of clustering algorithm is used in Rosetta clustering? EDIT:I meant to ask- when calculating the RMSD is the superimposing done pairwise in Rosetta clustering?

Parse error while reading in XML file in ROSETTA Scripts

Hello everybody,

I wanted to run a ROSETTA Scripts script to design a portion of a protein interface. But I struggle with an unexpected error, which appears to occur during reading in the XML protocol. I started the application with the following command line:

task_pack.restrict_to_repacking() not working

Dear Sir or Madam,
I am learning the "Monte Carlo Side-Chain Packing" in Workshop6.

After successfully typing

task_pack = standard_packer_task(pose),

I was trying to use

task_pack.restrict_to_repacking() .

However, I was told "MemoryError" (attached). Can someone tell me what is the reason? Thank you very much.

mutate_residue not working

Dear Sir or Madam,
Can I ask how to properly use the command of
mutate_residue(pose, 49, 'E') ?

It seems to be quite straightforward as pose name, residue number and amino acids are included into the parenthesis. However, I have been told
"MemoryError" (attached) after typing

from toolbox import mutate_residue
mutate_residue(A10, 3, 'E')

Do I need to type something else before using this command?

Basically, I want to mutate several amino acids into customised ones. Is this the best way to do?

HBNet and RosettaScripts

Submitted by protos_heis on Tue, 2014-08-05 06:05

I recently learned about a new Rosetta module for scoring hydrogen bond networks as part of protein design called HBNet. I was interested in trying out this module but I'm not sure how to use it. Recently I compiled one of the weekly releases of Rosetta3.5 so I think we have the most up-to-date software. HBNet is a RosettaScripts module I believe but I was wondering if someone could provide a sample XML script that I could play around with if it is not too much trouble. Thank you for your assistance!

Remodel: neighbor cutoff

Submitted by felipet on Wed, 2014-07-16 08:11

Hi

I am trying to design and sample a loop using Remodel. Residues that are interacting but farther away than 6 A are not being repacked (using the -find_neighbors) and I would like to increase the cutoff. How can I change this parameter?

thanks in advance

FloppyTail vs. Remodel for linkers

Submitted by attesor on Mon, 2014-07-07 08:36

I have a 11aa long linker (known sequence) connecting two parts of a protein (NOT two independent domains). I want to model the linker before some downstream Rosetta analysis on the protein. It seems FloppyTail is often suggested for the modeling of linkers.

My question is: how is FloppyTail compared to Remodel + Fixbb? What if I just insert some 11aa long extension (of any sequence) between the two parts using Remodel, then I use fixbb to mutate this newly inserted extension to the sequence of my linker? How would this compare to FloppyTail?

Failed glycine check when running RosettaRemodel to build disulfide

Submitted by cheyuk on Fri, 2014-06-27 02:31

Hi Rosetta users,

I was recently running RosettaRemodel to build a disulfide between two residues. The first residue is a gly and the second is tyrosine. I ran into this error:

"Failed glycine check. Cysteines cannot replace glycine positions in the native pose."

Is this because gly doesn't have a CB atom so that the CB-CB distance cannot be measured? I can think of mutating the gly to other residues as a workaround. But is there any other way to build a disulfide bond involving a gly using RosettaRemodel?
