Folks,

The following lines:

mdl.assess_dope(output='ENERGY_PROFILE NO_REPORT',
file=code+'.profile',
normalize_profile=True, smoothing_window=15)

are producing output files with a question mark in the name string.

ABC31_HUMAN.BL09950001.pdb?.profile

The question mark renders cp, mv and rename incapable of doing anything
with the file. Is there a way to prevent modeller from
appending the question mark to the created files?


Thanks,

Starr

If this is from your earlier script, you're getting 'code' from the
following bit of Python:
code = in_file.readline()
Note that readline() does not remove the line-end character(s), and
that's probably confusing Modeller. Try putting in
code = code.rstrip('\r\n')
after you read the line from your file.

You can just quote the filename, or escape the ? with a \ character, to
make cp, mv and friends work with it.

Dear MODELLER experts,

I have a target protein, whose X-ray structure is PARTIALLY available (the middle part, named domain B). There are two big regions missing (domain A & C) in the crystal structure, with more than 50 residues in each I would like to use MODELLER to model domain A & C, and there are templates available. I wonder if it is possible to include THE CONTENT OF domain B. in another word, to create a complete model of A-B-C while keep the coordinates of B domain fixed.

Any help/information will be greatly appreciated.
hi
its possible, just include the sequence of domain B in the ali file along with the seqence of domains A and B . the program will definitely orient the known structure with the calculated structure, but still u have to minimize it later on to infer the proper alignment
with regards
rathankar

Subject: [modeller_usage] To use separate templates for different
region of a protein
To:
Message-ID: <>
Content-Type: text/plain; charset="iso-8859-1"

Dear All,

With MODELLER, I wonder if it is possible to use different template(s) for different region of one target protein. For example, One protein has domain 1, 2 and 3. I would like to construct a complete model of this protein, with templates A and B for domain 1, templates C,D,and E for domain 3, and domain 2 already has coordinates/structure, which need to be preserved in the complete model.

Is there any way to do the above? If so, how? I tried to use the "inifile" feature and use the existing coordinate file of domain 2 as "inifile". while I got error message of " Atom index is out of range (iatm,natm)".

Any help/information will be very much appreciated.

Shirley
