Hallo all,
I have mutated my protein using mutate_selection.py and optimized it using optimize.py.

Optimize.py is giving me 5 models..but I don't know on what basis i should chose the best. Can  I use Dope and molpdf score for the same? How can I these  by running optimize.py?

thanks in advance.

Your original question was addressed just last week on the mailing list:
http://salilab.org/archives/modeller_usage/2012/msg00152.html

You make the alignment yourself, e.g. in a text editor. There is no
script to generate it for you automatically.

Either edit the PDB file to remove the region you don't want to include,
or see http://salilab.org/modeller/9.10/FAQ.html#2

Dear Modellers,
Tell me a preliminary aspect of the script Salign_Multiple_Struc.py
If multiple local folds are present in the computed alignment of this script for different templates, something like this,

Template1>---AAAAAA---BBBBBBBB----*
Template2>--APPPAAA---BCBBBB------*
Template3>----AAA----BBBBBBBB-----*
Template4>----AA-------BB---------*

Elaborate the factors considered by MODELLER to put template2 close to the template1, and why template3 and 4 are kept away from template1 and closer to template2.

Is it minimal RMSD of local template chunks, equal chunk lengths or something else. Give me the complete list of the considered factors considered in MODELLER for such a computation.

Best Regards
Ashish

Dear Modellers,
I sent this message a few days back too. What is the currently employed path to drive out of the reliable alignment mystery's vicious circle?

Hi,

I got the following error when trying to run a old python script (see
below) that worked very well before. A couple of days ago, I removed the
Java came from the system (Fedora 13) and installed Java from java.com
(jdk-7u4-linux-i586.rpm, jre-7u4-linux-i586.rpm) to fix a crash problem
of Jalview.

I wonder if the problem is related to the new Java or some other
problems.

Thank you.

To conclude: it turned out that each slave was running out of memory.
This is actually caused by a memory leak in Modeller that only affects
parallel loopmodel runs. A patch is available to fix the problem at
http://salilab.org/modeller/wiki/Patches
