I´m trying to model 5 SS bridges.When I try to tell modeller 9v1 to do that,I receive the following error:Could not find platform independent libraries <prefix>Could not find platform dependent libraries <exec_prefix>Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]'import site' failed; use -v for tracebackFile "test_ssmodel_fasciola.py", line 9def special_patches(self, aln):^IndentationError: expected an indented blockWhat might be wrong?The script,#Homology modelling by the automodel classfrom modeller import * # Load standar Modeller classesfrom modeller.automodel import * # Load the automodel class#Redefine the special_patches routine to include the additional disulfides#(this routine)class mymodel(automodel):def special_patches(self, aln):# A disulfide between residues 10-51,44-47,43-110,80-114,88-100:self.patch(residue_type='DISU', residues=(self.residues['10'],self.residues['51']))self.patch(residue_type='DISU', residues=(self.residues['44'],self.residues['47']))self.patch(residue_type='DISU', residues=(self.residues['43'],self.residues['110']))self.patch(residue_type='DISU', residues=(self.residues['80'],self.residues['114']))self.patch(residue_type='DISU', residues=(self.residues['88'],self.residues['100']))log.verbose() # request verbose outputenv = environ() # create a new MODELLER environment to build this model in# directories for input atom filesenv.io.atom_files_directory = './'a = mymodel(env,alnfile = 'test_fasciola.ali', # alignment filenameknowns = '1gmy_A.pdb', # codes of the templatessequence = 'Q8I7B2_sequence') # code of the targeta.starting_model= 1 # index of the first modela.ending_model = 1 # index of the last model# (determines how many models to calculate)a.make() # do the actual homology modelling
