Hello, I am a new user to Autogrow 4 and I am experiencing and error when trying to run the program on the PARP system from the tutorial. The error messages in the console are as follows:
We needed to make 2 ligands through Mutation
We only made 0 ligands through Mutation
Traceback (most recent call last):
File "RunAutogrow.py", line 675, in <module>
File "/home/william/Downloads/autogrow4/autogrow/autogrow_main_execute.py", line 83, in main_execute
smile_file_new_gen, new_gen_ligands_list = operations.populate_generation(vars, current_generation_number)
File "/home/william/Downloads/autogrow4/autogrow/operators/operations.py", line 181, in populate_generation
raise Exception("Mutation failed to make enough new ligands.")
Exception: Mutation failed to make enough new ligands.
Is there a reason that this error might be happening? I’m pretty sure that my Autogrow 4 installation and input commands are correct so any insight would be very much appreciated!

Hi William. Much thanks for your interest in AutoGrow4. This error occurs when AutoGrow can’t make enough mutants from the source compounds. I’d recommend using AutoGrow to evolve a larger population of ligands than just two, but you might be able to get it to work by reducing the value of parameters like
number_elitism_advance_from_previous_gen. You could also try removing any filters, such as
Hope this helps,
