Structural alignment of multiple chains
by Tal Weizmann 21 Dec '20

21 Dec '20

Hello, I would like to run structural alignment using all chains of the same protein with salign (different PDB files). Can I do that with modeller?

modeling two chains while preserving their structural orientation wrt each other
by shivu shiv 04 Dec '20

04 Dec '20

Dear All, I am working on modeling a protein with two chains (heterodimer). I have used two separate pdb files for each chain and oriented the two template structures appropriately before the modeling. Modeller is able to model both the chains, however not preserving the orientation of both the chains. I am seeking suggestions for how to specify restraints to preserve the orientation of both the chains with respect to each other. Please provide your suggestions. Thanks and Regards shivu

Dear users, I am having trouble to use the SOAP score. I already read the manual and tried to find tutorials online but none addressed the issues I am having. I downloaded the SOAP-Protein potential file from the SOAP website and placed at C:\ProgramFiles\Modeller9.25\lib\x86_64-w64, uncommented the SOAP-related lines in model-single.py but when i try to run the script i receive an error: hdf5err____E> unable to open file Here's a description of what I get back from the code: MODELLER … [View More]9.25, 2020/09/03, r11894 PROTEIN STRUCTURE MODELLING BY SATISFACTION OF SPATIAL RESTRAINTS Copyright(c) 1989-2020 Andrej Sali All Rights Reserved Written by A.
