Constraint contributors

Filter structures by radius of gyration.

API Reference

ConfigGyrationRadiusConfig Source

Configuration for gyration radius constraint.

number

default:"45.0"

Maximum acceptable radius of gyration in Ångströms (lower values are more compact).

ReturnsConstraintOutput

Per-proposal score in [0.0, 1.0] with gyration_radius and longest_alpha_helix metadata. Sequences without a structure receive MAX_ENERGY and no metadata.

Usage

python

from proto_language.core import Constraint
from proto_language.constraint import gyration_radius_constraint, GyrationRadiusConfig

constraint = Constraint(
    inputs=[segment],
    function=gyration_radius_constraint,
    function_config=GyrationRadiusConfig(
        # Configure parameters here
    ),
)

scores = constraint.evaluate()
