Hello Ben thank you for your kind update:). I did not set one of the starting and ending numbers incorrectly, please see this below pasted script and let me know if there is a way I can generate these 500-models? (maybe because I am requesting too many residues?) Thanks:) Joel # 17 residue insertion return Selection(self.residue_range('85:A', '102:A'), self.residue_range('518:B', '535:B'), self.residue_range('951:C', '968:C'), self.residue_range('1384:D', '1401:D'), self.residue_range('1817:E', '1834:E'), self.residue_range('2250:F', '2267:F'), self.residue_range('2683:G', '2700:G')) m = MyLoop(env, inimodel='7dwb_fill.B99990001.pdb', # initial model of the target sequence='7dwb') # code of the target m.loop.starting_model= 1 # index of the first loop model m.loop.ending_model = 500 # index of the last loop model m.loop.md_level = refine.slow # loop refinement method; this yields # models quickly but of low quality; # use refine.slow for better models m.make() On Tue, Oct 4, 2022 at 10:56 PM Modeller Caretaker < modeller-care@salilab.org> wrote: > On 9/28/22 4:55 AM, Joel Subach via modeller_usage wrote: > > for the above topic I can not seem to generate more than > 1-model, although > > my script indicates 500 models.
