Problems with ligand when running RosettaLigand

Hi there,
I am relatively new to Rosetta and have been trying to get my head around RosettaLigand. I have run into a problem with the pdb files that I get out from a run.
In some instances when I run the Rosetta ligand docking, the pdb files that come out for each run show the ligand docked in a logical position. However, the ligand itself is modified to display extra bonds between some atoms that were not in the input/native pdb files.
Is there any way that I can stop this from happening?
Thanks very much.

mover "RepackMinimize" does not support chains > 2?

In RosettaScript, the mover "RepackMinimize" has attributes "design_partner1" and "design_partner2" to define which partner will be designed, but it does not have attribute like "jumps" or "partners" (just like "DockingProtocol") to let you set the jump in fold tree. It assumes to use jump=1, this is OK for two-chain complex. But it is not OK for more than two chains.

I applied this mover on a 4-chain complex with "minimize_rb=1":
<RepackMinimize name=des1 scorefxn_repack=soft_rep scorefxn_minimize=soft_rep minimize_bb=0 minimize_rb=1/>

But the program halted with errors:

in silico affinity maturation design

Two years ago, Fleishman & Whitehead and their colleagues published on Science a paper about their encouraging work of de novo design new proteins targeting HA. This work was intended to be a general computational method for designing proteins that bind a specific surface patch on a target, while the success ratio was rather low and it was likely there is a long way to go.

So I am curious if there is any progress in this area, is there already some stable/pilot protocols of in silico affinity maturation that can be followed to be applied in similar works?

modeling 4 linkers between 2 domains

Hi, I am modeling linkers between domains. There are 2 domains connected by 4 linkers. When I run FloppyTail application, domain docking is performed as if there are 5 domains sequentially connected by 4 linkers. Is there a way to define movemap so that rosetta will consider 2 domains out of 5 as one domain, and the other 3 domains, as another, so that there are 2 domains.

Thanks

Here are my flags

-database /rosetta3.4/rosetta_database/
-in:file:s infile.pdb
-in:file:movemap linksfile
-packing:repack_only
-nstruct 30000
-out:output
-out:file:silent linker_model.out

HBondEnergy

Hi,

I want to know that how can I access the HBondEnergy of residue residue pair of the HBondSet(). I checked that there is a function called hbond.energy(), but don't know how to use that ?? But when I use it for the residue in pdb to store information using :
for residue in range(1,p.total_residue()+1):

for hbond in range (1,p_hb.nhbonds()+1):
hbond = p_hb.hbond(hbond)
donor = hbond.don_res()
acceptor = hbond.acc_res()
if residue == donor or residue == acceptor:
donor_residues.append(donor); acceptor_residues.append(acceptor)

Fragments picker: -nohom option seems not to work

Hello everyone

I run the following command: etc/make_fragments.pl -nohoms -id fragm blabla/protein.fasta

and I obtain fragments files which contain fragments from the original protein.

moreover running the same command without the -nohoms option I obtain the same output.

Does anybody know why?

Thanks in advance

Alfredo

Feedback for Loopmodeling module

Working with Loop-modeling to rebuild some missing loops from crystal structures. I don't see an issues tracking system for Rosetta, so I'm posting a couple of suggestions here:

- The -override flag is required to continue running loopmodel when the out files are already present. Without this the program aborts with no error messages. Is it possible to add in clarification in the log file when this happens? Very difficult to debug for people who are learning.
