Hi,
Please make sure that you define
SET ATOM_FILES_DIRECTORY = ....
One more thing: make sure that your PDB file doesn't have a chain
identifier (A, B, C, etc), or make sure that your .ali file has one
(currently it's empty), but I guess you already know this.
NB. Would you please post any questions you might have in the future on
the list first, because other people might have the same problem and may
benefit from or already have the answer as well.
Good luck,
Bozidar

Subject: Reading_PDB_File
Hello,
I need a help.
My task was to see if we can model sequence with unknown structure which
has >90%
similarities (Protein Blast) to our X-Ray determined structure recently
deposited to PDB
from our Structural Genomics Project (MCSG; http://www.mcsg.anl.gov ).
The known structure name is: 1g2r. I named sequence my_ 15900466 (Where
I can find rules for assigning a
name to unknown structure?).
I tried DESCRIBE with following .top file:
--
SET OUTPUT_CONTROL = 1 1 1 1 2
SET ATOM_FILES = '1g2r', ALIGN_CODES = '1g2r'
READ_MODEL FILE = '1g2r', MODEL_SEGMENT = '@:@' 'X:X'
DESCRIBE
--
There were no problems. I've got nice report in .log file.
When I tried to run modelling .top:
--
INCLUDE
SET ATOM_FILES_DIRECTORY = './:../atom_files'
SET ATOM_FILES = '1g2r', ALIGN_CODES = '1g2r'
READ_MODEL FILE = '1g2r', MODEL_SEGMENT = '@:@' 'X:X'
SET SEGFILE = 'align-jerzy.seg'
SET KNOWNS = '1g2r'
SET SEQUENCE = 'my_15900466'
SET OUTPUT_CONTROL = 1 1 1 1 2
CALL ROUTINE = 'full_homol'
--
where align-jerzy.seg is:
--
>P1;1g2r

It created align-jerzy.seg.ali,
but it stopped on full_homology when reading .pdb file,
which it read properly for describing protein.
Here it is 25 last lines from .log file (tail -25 ..):
