hay que darle prosa, hay gente trabajando docking sobre este receptor, haber
si te inscribes al firo de autodock.

Hi All

Thanks everyone for responding to the queries.
I have one more doubt. Every time i finish the whole of the docking
procedure, I try to view the interactions between the ligand and the
receptor
(Analyze -> Docking -> Show interactions)

But it opens up a Python shell window and shows me the following errors...

File "/usr/local/MGLTools-1.4.6/MGLToolsPckgs/ViewerFramework/VF.py", line
714, in tryto
   result = apply( command, args, kw )
File
"/usr/local/MGLTools-1.4.6

line 1922, in doit

line 44, in __init__
   self.build(detect_pi=detect_pi)

   self.buildHydrogenBonds()           #

"/usr/local/MGLTools-1.4.6/MGLToolsPckgs/MolKit/interactionDescriptor.py",
line 117, in buildHydrogenBonds
   lig_gly_res = d['lig_hb_gly_res'] = lig_hb_res.get(lambda x:
x.type=='GLY')
UnboundLocalError: local variable 'lig_hb_res' referenced before assignment

Could anyone please help me fix these errors. I tried changing the Grid
and Docking parameters. But its of no help.

Thanks in advance

Hi,

I didn't search your archives to see if this was mentioned before,
but I didn't see it listed in your faqs...

When screening a large library autodock4 fails to converge in
about 0.5% of the compounds listed. In those cases, I see the
message:

NOTE: All energies are equal in population; re-initializing....

endlessly repeated in the log file, which grows very large. I am not
sure if this is a bug in the initialization, but in my opinion the
program should exit in such a case more gracefully. I never see this
string in any of successful fits, which would indicate to me that
the program has hit en error condition from which it can't escape.
So my suggestion would be to better deal with the initialization, or
change the output message to better reflect the true error condition,
whatever it is.

I should also mention that some of the compounds miraculously do
converge if I just restart the program. I don't know how the program
works, but my interpretation of this symptom would be that you use
time to initialize the random seed of your GA, and then when I restart
it I get a better initialization. However, when the program gets stuck
in this loop, even though it says that it reinitializes, it never actually
does. Does that seem plausible?

Thanks, -Borries

Hi,

I thought I would point out that 2I35 is a low resolution rhodopsin
structure.  The beta2-adrenergic receptor file is 2RH1 with the T4 lysozyme
structure.  You can remove the residues from 1002 to 1161 to eliminate the
inserted protein.  Many GPCR structures are built without knowing the exact
loop structures.
