External Source Sequence Alignment
by Li,Haoxi 05 Oct '20

05 Oct '20

Dear Modeller Users, Hope this email finds you well! I have a question about building homology models with sequence alignments coming from external sources (BLAST, PROMALS3D, etc). Since PIR format alignment files are usually not provided by these sources, do I need to manually construct the file based on the alignment I have? Are there any other ways? Thank you so much! Best wishes, Haoxi

loop.py
by Jeff Reneker 24 Sep '20

24 Sep '20

Following the example in “Refining an existing PDB file” I want to “refine a region of an existing PDB file without comparative modeling.” The first thing I want to do is to get the loop.py script in the examples to work for any other structure. The only change I made is in this block of code from loop.py where I substitute 6aa0 for 1fdx as follows: m = MyLoop(env, inimodel='1fdx.B99990001.pdb', # initial model of the target sequence='1fdx', # code of the target loop_assess_methods=assess.DOPE) # assess loops with DOPE # loop_assess_methods=soap_loop.Scorer()) # assess with SOAP-Loop m = MyLoop(env, inimodel=‘6aa0.pdb', # initial model of the target sequence=‘6aa0', # code of the target loop_assess_methods=assess.DOPE) # assess loops with DOPE # loop_assess_methods=soap_loop.Scorer()) # assess with SOAP-Loop Then, I copy the 6aa0.pdb file to the appropriate directory. This is the error message at the tail end of the output: Traceback (most recent call last): File "loop.py", line 35, in <module> m.make() File "/usr/lib/python3.6/dist-packages/modeller/automodel/loopmodel.py", line 37, in make self.build_seq(self.inimodel, 1) File "/usr/lib/python3.6/dist-packages/modeller/automodel/loopmodel.py", line 169, in build_seq atmsel = self._check_select_loop_atoms() File "/usr/lib/python3.6/dist-packages/modeller/automodel/loopmodel.py", line 398, in _check_select_loop_atoms atmsel = self.select_loop_atoms() File "loop.py", line 18, in select_loop_atoms return selection(self.residue_range('19:', '28:')) File "/usr/lib/python3.6/dist-packages/modeller/coordinates.py", line 329, in residue_range start = self.residues[start]._num File "/usr/lib/python3.6/dist-packages/modeller/coordinates.py", line 259, in __getitem__ (self.offset, self.length, self.suffix)) File "/usr/lib/python3.6/dist-packages/modeller/util/modutil.py", line 23, in handle_seq_indx int_indx = lookup_func(*args) File "/usr/lib/python3.6/dist-packages/modeller/coordinates.py", line 323, in _indxres raise KeyError("No such residue: %s" % indx) KeyError: 'No such residue: 19:' So, I’m not sure what the deal is because that’s how new I am to Modeller. Thanks, JR.

Modeller 9.25 release
by Modeller Caretaker 09 Sep '20

09 Sep '20

A new version of Modeller, 9.25, is now available for download! Please see the download page at https://salilab.org/modeller/ for more information. If you have a license key for Modeller 8 or 9, there is no need to reregister for Modeller 9.25 - the same license key will work. (It won't do any harm to reregister if you want to, though!) 9.25 adds binaries and installation packages for Linux on both 32-bit and 64-bit ARM (e.g. on Raspberry Pi), allows overriding the prefix for automodel output file names, and fixes a number of bugs. See the Modeller manual for a full change log: https://salilab.org/modeller/9.25/manual/node40.html If you encounter bugs in Modeller 9.25, please see https://salilab.org/modeller/9.25/manual/node10.html for information on how to report them. Note: you are receiving this email either because you subscribed to the modeller_usage mailing list, or you provided this address when you requested a Modeller license and you ticked the "notify me of new releases" box. In the latter case, if you no longer wish to receive announcements of new Modeller releases, simply reply to this email and let us know.

Socket modules and Chimera
by Casey Becker 31 Aug '20

31 Aug '20

Hello, I'm working with parallel jobs, and I can run them fine directly through IDLE, but when I try to run them through Chimera, I get an error that I lack the socket module necessary to make them work - hence me using IDLE instead. However, I would really like to be able to run my scripts directly through Chimera, but I'm having trouble finding a fix to make this happen. I've attached the two scripts I'm currently using, as well as the reply log message. Thank you.

Question automodel from NMR
by Brian Wiley 14 Aug '20

14 Aug '20

Hi Ben/Team, I can't seem to find documentation on this. If I am modelling a sequence through a PDB file that was an NMR experiment with 10 or 20 models, how does Modeller handle this? Does it just chose the first model list in PDB? Thanks, Brian

Modeller Model Building Inquiry using existing PDB cooridnates
by Joel Subach 13 Aug '20

13 Aug '20

Hi I want to build a C and N tail and one cytoplasmic loop that are missing from the PDB Cryo-EM 3-D coordinate file of a transmembrane protein. These regions were too dynamic during their Cryo-EM process and therefore are left out of the structural file that the investigators input into the PDB. Is there a way to model just these missing tails and one loop WITH the rest of the protein meaning not modeling the regions separately and then stitching them into the existing PDB coordinate file subsequently? I did not see this methodology amongst the Modeller tutorials but think it is best to maintain the fidelity of the protein as a whole i.e. non-stitching. Thanks:) Joel

Change ROOT_NAME for automodel.make()
by Brian Wiley 07 Aug '20

07 Aug '20

Hi, I thought this would be extremely easy to find if you can do, but I guess not. I would like to be able to change the ROOT_NAME of the model from automodel.make(). For instance: a = automodel(env, alnfile = 'TSC2_6ssh.ali', knowns = ('6ssh'), sequence = 'TSC2_HUMAN') a.make() # Here I want the prefix to be 'TSC2_6ssh' and not 'TSC2_HUMAN' so all files and pdb file at end would be TSC2_6ssh.B99990001.pdb Is this possible?
