Loop Modeling

[Anonymous]

Hi,

I am trying to take the output from the relax module and put it into the loop modelling module. I’m getting the following errors:

I did not get any errors while running the relax mode, so I don’t think it is a formatting problem. Any advice would be appreciated!

Thanks!

You’ve got a centroid/full atom mismatch.

It looks like your relax result is fullatom, but your loop modeling is in centroid mode. You probably need to pass a flag to loop modeling to make it run in full atom mode – hopefully the loop modeling documentation shows which one. (It’s pretty dumb that you need a second flag for this, I know…)

I get the same errors when I run the loop modelling demo that came with the Rosetta3.0 package. Has anyone gotten this demo to run w/o getting warning messages? Is the demo incorrect? It looks the demo is reading it in as a full atom, despite only backbone being provided. However, I still get errors when I remove the full atom from the flags file.

Here are the errors from the demo.

Thanks for your help. I figured it out. I needed -loops:fa_input

It still doesn’t explain why the demo won’t work, but my case does work now.
