Description

This floe takes all antibody structures from the input dataset(s) and clusters them based on the CDR surface patches. These patches are based on SiteHopper patch generation. Input systems could be of a single antibody in multiple configurations, difference antibodies, or a combination of both.

Limitations: Due to the limits of clustering, this floe is not suitable for systems with only a handful of structures. The greater the number of input structures, the better clusters can be defined.

Potential Input Sources: Antibody Sequences to 3D Models Floe, Antibody Experimental Structure Prep Floe

SiteHopper Parameters

Sequence Numbering Scheme (numbering_scheme): This parameter sets the numbering scheme applied to antibodies.

  • Required

  • Type: string

  • Default: IMGT

  • Choices: [‘IMGT’, ‘Chothia’, ‘Martin’, ‘Kabat’]

Chunk Size (chunk_size): Control chunk size for patch overlays.

  • Required

  • Type: integer

  • Default: 50

Cube memory for NxN cube (aggregator_memory): Controls the memory needed to processes the NxN matrix. Memory requirement is dependent on input size N=10k ~0.1GB, N=100k ~10GB.

  • Type: decimal

  • Default: 1800

Distance Cutoff (distance_cutoff): Sets the distance cutoff when running clustering on the distance matrix.

  • Type: decimal

  • Default: 2.0
