Hi, The alignment file should contain: structureX for templates and SequenceX for the target. Why started from model 3:starting_model= 3? hope this help, Yours, Riadh HAMMAMI PhD Student University of Tunis El Manar, TUNISIA »»»»»

Your script is:

from modeller.automodel import * # Load the automodel class

log.verbose()

# Override the 'select_atoms' routine in the 'automodel' class class mymodel(automodel): def select_atoms(self): self.pick_atoms (selection_segment=('923:','924:','925:','926:','927:','928:','929:','930:','931:','932:','933:','934:','935:','936:','937:','938:','939:','940:','941:','942:','943:','944:','945:','946:','947:','948:','949:','950:','951:','952:','953:','954:','955:','956:','957:','958:','959:','960:','961:','962:','963:','964:','965:','966:','967:','968:','969:','970:','971:','972:','973:','974:','975:','976:','977:','978:','979:','980:','981:','982:','983:','984:','985:','986:','987:','988:','989:','990:'), selection_search='segment', pick_atoms_set=1, res_types='all', atom_types='all', selection_from='all', selection_status='initialize')

env = environ() # directories for input atom files env.io.atom_files_directory = 'C:\master' # selected atoms do not feel the neighborhood env.edat.nonbonded_sel_atoms = 2

a = mymodel(env, alnfile = 'fosfalcapirstrano1daq.ali', # alignment filename knowns = '1DAQB', # codes of the templates sequence = '14521248') # code of the target
