Good o know about those options. I was just skimming through section 2 in the manual over lunch and I came across this example script. Would this also work? If so, are there any advantages to using model-segment.py?

2.2.9 Using your own initial model Normally, automodel generates an initial model by transferring coordinates from the templates. However, if you have a prepared PDB file containing an initial model, you can have automodel use this instead with the inifile keyword, as in the example below. (This automatically sets automodel.generate method to generate.read xyz for you, which is necessary for this to work.) Example: examples/automodel/model-myini.py # Modeling using a provided initial structure file (inifile) from modeller import * from modeller.automodel import * # Load the automodel class log.verbose() env = environ() # directories for input atom files env.io.atom_files_directory = [’.’, ’../atom_files’] a = automodel(env, alnfile = ’alignment.ali’, # alignment filename knowns = ’5fd1’, # codes of the templates sequence = ’1fdx’, # code of the target inifile = ’my-initial.pdb’) # use ’my’ initial structure a.starting_model= 1 # index of the first model a.ending_model = 1 # index of the last model # (determines how many models to calculate) a.make() # do homology modeling
