Quick question, I am interested in refining a few homology models with long runs of the relax protocol. I find the run time is fairly short on my local supercomputer system, and I’d like to make maximum use of the resources available to me. So, how do I improve my models by refining for a week instead of just a few minutes without having the job exiting? (Note: I believe the run exits normally.)
Also, is there a good order to use the applications when it comes to relax / loop modeling / backrub?
Thanks,
Rob

The most obvious suggestion is to increase the number of models you generate for each input structure (e.g. by increasing the parameter to -nstruct). Almost all Rosetta protocols are stochastic, so there’s a chance that any given run will get hung up in a local minimum. Typically people will run hundreds to thousands of structures, and then pick the “best” models from the set.
Aside from that, I’m not sure that performing longer runs would necessarily provide you with any better results. I’m not really a relax user, but it’s my understanding that at a certain point, you basically reach convergence and start “drilling down” in the energy function without much change/improvement to the actual structure. (Keep in mind that the Rosetta energy function isn’t perfect and is rather rugged at fine scales, so those last several energy units 1) might not take you closer to the native structure and 2) might result in structures insignificantly different than those from a shorter run.) Is there some reason to suspect that the output structures are sub-optimal? If so, you might have better results trying other protocols, rather than just a longer relax.

Basically, I am trying to maximize the quality of the model to make one that is suitable as a search model for molecular replacement. I’m not sure if that’s realistic, but the current model I have isn’t working, so I thought I’d give it a try.
Any ideas regarding the second question as to whether order matters for relax, loop modeling and backrub?

Hi,
I was just trying out the example from the paper listed above (without including the map just yet) — I keep running into this error:

Also, I tried another case where I just used the words “target” “template” etc… without the specific details and no luck. Am I missing something obvious?
Thanks.

Looking at the code around the error, I think your problem may be in your alignment file. No template PDB at all should spit a critical error (crash) “ThreadingJobInputter needs parent-pdbs either as in:file:template_pdb or as in:file:template_silent “. This error occurs at the end of a search for the appropriate alignment – I guess from that .ali file….? (In case you can’t tell I’ve never used the threading inputter…)
By the way, the -overwrite suggestion is a red herring; normally if no jobs are completed it’s because someone re-ran a job where the results already existed. so overwrite is suggested. Here, no jobs are created (because of the failure in figuring out alignments with which to create them); no jobs created = no jobs run = overwrite hint.

My alignment file is in this format.
## FJ637 2h1q.pdb
# hhsearch
scores_from_program: -999 100.00
7 RIKKKAMELA (…) ESESIKYVIE
5 EIYDAMINGI (…) YSAGQKVTIK
—And, like I say, the 2h1q.pdb is in the directory and when I open it it seems like a very normal file:
ATOM 1 N PHE A 1 -0.433 28.290 54.674 1.00 88.88 N
(…)
ATOM 1867 OXT LYS A 247 0.587 32.549 77.191 1.00 56.78 O
TERAnd, for reference, here’s the fasta file:
>NP_143367.1 gi|14591289|ref|NP_143367.1| hypothetical protein [Pyrococcus horikoshii]

Hello,
Sorry for the slow response to this.
Rocco’s comments on sampling are correct. With relax alone, generally more than 5-10 structures are overkill; if you want to best spend large amounts of computer time, then exploring larger conformational changes with looprelax is preferred.
Regarding the error, this is a minor bug in the ThreadingJob inputter. If you change the first line of the .ali file to read:
## FJ637 2h1q
(dropping the ‘.pdb’) then it should work.-Frank DiMaio

If you’re attempting to use models for molecular replacement, you’ll probably be interested in the following paper:
DiMaio et al. “Improved molecular replacement by density- and energy-guided protein structure optimization.” (2011) Nature, doi:10.1038/nature09964
My understanding is that, while lower energy structures in the Rosetta energy function were more likely to give good results, having a large diversity of structures and a thoroughly sampled conformational space was also key to finding a good search model. So instead of taking a single structure and really optimizing it with relax, its likely better to create a range of structures, and consider each of them for molecular replacement.
For the ordering, you’re probably best served by loop modeling, then backrub, then relax. That is, going from more course, drastic operations to finer, more refinement operations. Loop modeling makes big changes to backbone structure, whereas backrub makes finer, more local changes, and relax is to some extent a final minimization step. Another technique to try is to apply them in cycles to walk from one minima to the other. (Loop modeling moves you to another region of search space, and then backrub and relax reorganizes you around that new conformation, which sets you up to find a different set of conformations in the next round of loop modeling.)
