Benn, CASP winners used HMM based profiles for target as well as template to rank and consider the template hits. Their approach is better when the target sequence identity to known templates lie below the twilight zone mark.

Many thanks, Since Modeller is a package for comparative modeling, if you don't have a template, you cannot model that region of your model. I don't know what you mean by "Modeller ... doesn't suggest templates" since Modeller doesn't suggest templates for you. Perhaps you mean you are doing a sequence-sequence search to look for templates (step 1 of the basic tutorial) and you didn't find any? BLAST does essentially the same thing - except that it's using an approximation rather than "real" dynamic programming, so it runs faster - so is also unlikely to find a template if this search doesn't work. ModWeb supplements this basic sequence-sequence search with more sensitive profile-based searches (it also tries PSI-BLAST, which is a similar method). But there are many other methods available to search for templates - e.g. HMM-based. One thing you could do is look at the best performers for the last CASP contest and see how they detect templates - some of those are available as web servers.

But Benn, you answer my simple question then. Suppose you have 2 protein sequences for each of which you generated 1000 decoys. To select the best model, won't you consider normalized_DOPE. Energy & GA341 can discriminate bad and correct overall model fold to some extent, but it can't cluster/select best model especially, when we consider TBM-HA targets. And, By the way i designed an algorithm for which i am writing the script which does calculate most likely GDT-TS or GDT-HA score to actual native unknown conformation. And yes, don't mind about my comments on DOPE. I experienced it, So wrote it.

Dear Marco, Your question is very nice. But to make a good prediction, better check out structural similarity in templates based on the both N & C terminal. I guess you are modeling a big sequence, which may have multiple domains. So you should consider many things. If you upload other details of the sequence along with its length, it will be better to suggest the best way to screen significant template folds.

Regarding Salign
by Ashish Runthala 01 Mar '11

Dear Modellers, How does align2d_mult actually adds the target sequence onto the aligned templates ali file. What is the logic considered by align2d_mult to align the target sequence onto the structurally aligned templates' ali file.It just considers topology of coordinates but no structural information is known for target. So how does it considers restraints from templates to align target sequence?

Dear Albert, It will be really a big mess to select best decoy. Use this line in your modeling script in the loop like this, and use redirectional operator while running the modeller as model_mult.py > modeling.log. That will solve your purpose. knowns=(........), sequence='.....', assess_methods=(assess.DOPE,assess.GA341,assess.normalized_dope)) a.starting_model=1 This will solve your purpose.

If you can send me your full inputs (which two PDBs are you trying to align?) I'll see if it can be fixed.

So I cannot obtain the DOPE or MOLPDF information for each residues. I am wondering, is it possible to rank then manually? Thank you very much
