Docking

Dear Rosetta Team,

When docking a protein with a solid surface, Rosetta will need a .surf file; Any one can tell me how to setup/edit a .surf file for a certain solid surface (a .pdb file) for surface docking? In the demo example for the calcite.surf, there is not detailed instruction to tell how to do it? Only three lines, with likely X,y,z in the calcite.surf file. I dont know what they are representing for a solid surface?

Thanks

I am attempting to dock a peptide onto a protein using flexpepdock. The docking completes and the identified structures are plausible solutions. However, when I examine the score.sc file, I notice that the I_hb term has a single, extremely high value for all structures:

I_hb = 18446744073709551616.000

I am prepacking the structure before docking:

FLEXPEP -s PEPTIDE.pdb -flexpep_prepack -ex1 -ex2aro -overwrite

FLEXPEP -s PEPTIDE_0001.pdb -pep_refine -ex1 -ex2aro -nstruct 100 -lowres_preoptimize -native PEPTIDE_0001.pdb

Hello,

I was using Rosetta 2016.02 "local  refinement" to calculate the interface scores of known protein complexes (in a bound form).

Now, I tried docking the same protein complexes, with exactly the same flags with Rosetta 2018.21. I realized that the content of the score file has changed and it gives totally different I_sc and total_score.  Almost any protein complex that I tried gives favorable results now (i.e. I_sc < -5).  Why is this the case? 

I couldn't find what has changed since 2016.02 version.
