Gigadock Warp Classic

Description

Approximates a full Gigadock run with a mixture of FastROCS and docking.

  1. Dock a random subset of molecules

  2. Cluster top docked molecules and select top scoring cluster heads

  3. Runs FastROCS on all input molecules using top scoring poses from the previous step as queries

  4. Re-dock the top scoring molecules from FastROCS

  5. Output Hit List of top scoring docked molecules.

Parameters

Inputs

  • Design Unit or Receptor Dataset(s) Dataset with the design unit (DU) (or old format receptor) to dock to. Multiple design units are allowed up to a limit of 10 for the Hybrid dock method (see ‘Docking Method’ parameter) and 2 otherwise. The behavior with multiple design units depends on the docking method. For ‘Fred’ or ‘FastFred’ each molecule will be docked to each design unit and the results from the best scoring design unit will be outputted, thus docking time (and cost) will scale roughly linearly with the number of design units. For ‘Hybrid’ each molecule will be docked only into to the design unit with the crystallographic bound ligand most similar (by ROCS Combo Tanimoto) to the molecule being docked, and docking time (and cost) will increase roughly by roughly 5% per addition design unit.
    Type : data_source
    Required : True
    Python Name : init_input_dataset
  • Input Conformer Collection Input collection containing molecules to dock. The collection should have been created by the ‘Prepare Giga Collections’ floe. Several large pre-generated 3rd party vendor docking collections can be made available in to your organization upon request at no charge by e-mailing support@eyesopen.com (if your organization has already requested them you will already have to these pre-generated collections). The collection will be located in the ‘Organization Data->OpenEye Data->Gigadocking Collections’ folder which also automatically contains several smaller collections and collections containing random subsets of the larger vendor collections.
    Type : collection_source
    Required : True
    Python Name : molecule_input_collection

Outputs

  • Hit List Dataset Output dataset with the top scoring docked molecules.
    Type : dataset_out
    Required : True
    Default : Gigadock Warp Hit List
    Python Name : hit_list_output_dataset
  • Queries Output dataset with the queries used by FastROCS. The queries are the cluster heads of the top scoring poses from the initial docking of a random subset of molecule from the input collection.
    Type : dataset_out
    Required : True
    Default : Gigadock Warp Queries
    Python Name : queries
  • Output Design Unit(s) Dataset Output dataset containing a copy of the design unit(s) docked to.
    Type : dataset_out
    Required : True
    Default : Gigadock Warp Design Unit
    Python Name : output_design_units_dataset
  • Temporary Collections This temporary collection is used by the floe during the run and automatically deleted at the end of the run.
    Type : collection_sink
    Required : True
    Default : Gigadock Warp Temporary Collection
    Python Name : temporary_collections

Options

  • Hit List Size Size of the final hit list with the top scoring docked molecules.
    Type : integer
    Required : True
    Default : 10000
    Range : 1 to 100000

  • Docking Method Docking method to use. ‘Fred’ is the default structure based scoring method. ‘Hybrid’ biases the the docking towards poses that overlay the crystallographic ligand (the design unit(s) must have a bound ligand). ‘FastFred’ is a faster variant of ‘Fred’ (typically ~2x faster for single design units) that samples less and uses a simpler scoring function in the initial stages of docking.
    Type : string
    Required : False
    Default : Fred
    Choices :Fred, Hybrid, Fast Fred
    Python Name : docking_method

    Range : 0.0 to 0.1

    Type : decimal
    Required : False
    Default : 0.08
    Range : 0.0 to 0.1

    Required : True
    Default : False
    Choices :True, False
    Python Name : cluster_fastrocs_queries

GPU Hardware

This parameters control the AWS instance type the FastROCS Cube will use. There is in general no reason to adjust these. They are exposed because overall demand for GPU instances on AWS has occasionally been very high and this has lead to extremely long run times for this floe as it waits for GPU instances in some circumstances.

  • FastROCS Instance Type The instances excluded by default are known to be not cost effective for FastROCS.
    Type : string
    Required : False
    Default : !g4dn.metal,!g5.12xlarge,!g5.24xlarge,!g5.48xlarge,!g4dn.12xlarge,!g3s.,!p3.
    Python Name : fastrocs_instance_type
  • Spot instance policy for FastROCS GPU Instance. To run on SPOT instances use the default setting of ‘preferred’. To run on ON-DEMAND instances set the value to ‘prohibited’. ON-DEMAND instances typically cost x3-4 more than SPOT instances, but are more available than SPOT instances when overall demand for GPUs on AWS is high.
    Type : string
    Required : False
    Default : Required
    Choices :Allowed, Preferred, NotPreferred, Prohibited, Required
    Python Name : spot_instance_policy_for_fastrocs_gpu_instance

Output Fields

These parameters allow the user to change the default output fields this floe creates in the output datasets and/or collections. Note that parameters identifying a molecule field are special. If a molecule field is left empty the floe writes the molecule to the primary (i.e., default) molecule field of the record. The primary molecule of a dataset can be identified in the UI by looking for star on its field badge. CAUTION: If these parameters are modified the modifications must also be applied to the input fields of downstream floes that read fields written by this floe. If the downstream floe does not support specifying the input field then they may not work properly with the output of this floe if these settings are modified.
