create_genetic_algorithm_design(assay, criteria, num_steps=25, pop_size=1024, n_offsprings=5120, crossover_prob=1.0, crossover_prob_pointwise=0.2, mutation_average_mutations_per_seq=1, allowed_tokens={})[source]#

Start a protein design job using a genetic algorithm based on assay data, a trained ML model, and specified criteria.

Parameters:

  • assay (AssayDataset) – The AssayDataset to design from.

  • criteria (Criteria or Subcriterion or Criterion) – Criteria for evaluating the design.

  • num_steps (int, optional) – The number of steps in the genetic algorithm. Default is 25.

  • pop_size (int, optional) – The population size for the genetic algorithm. Default is 1024.

  • n_offsprings (int, optional) – The number of offspring for the genetic algorithm. Default is 5120.

  • crossover_prob (float, optional) – The crossover probability for the genetic algorithm. Default is 1.0.

  • crossover_prob_pointwise (float, optional) – The pointwise crossover probability for the genetic algorithm. Default is 0.2.

  • mutation_average_mutations_per_seq (int, optional) – The average number of mutations per sequence. Default is 1.

  • allowed_tokens (DesignConstraint or dict of int to list of str, optional) – A dict of positions and allowed tokens (e.g. {1: [‘G’, ‘L’]}) designating how mutations may occur. Defaults to empty dict.

Returns:

A future object representing the design job and its results.

Return type:

DesignFuture

class openprotein.design.DesignFuture[source]#

A future object that will hold the results of the design job.

__init__(session, job=None, metadata=None)[source]#

Construct a future for a design job.

Takes in either a design job, or the design metadata.
