Fragment Molecule for Torsion Scans

This cube identifies all rotatable bonds in a molecule and creates a fragment for each maintaining the chemical environment around the rotating bond. Atoms are tagged to specify the rotatable torsion in each fragment and emitted through the success port. Each fragment is labeled with its parent molecule. Records for the parent molecule are sent out the ‘parent_output’ port so that calculations performed on the fragments can be regathered with the parent in other cubes.

Calculation Parameters

  • atom tag (string) : Tag for the atoms in torsion
  • CPUs (integer) : The number of CPUs to run this cube with
    Default: 1 Min: 1 Max: 128
  • Cube Metrics (string) : Set of metrics to be collected

    Choices: cpu, disk, memory, network
  • Temporary Disk Space (MiB) (decimal) : The minimum amount of disk space in MiB (1048576 B) this cube requires. Due to overhead, request a couple hundred MiB more than required.
    Default: 5120.0 Min: 128.0 Max: 8589934592
  • GPUs (integer) : The number of GPUs to run this cube with
    Default: 0 Max: 16
  • Instance Tags (string) : Only run on machines with matching tags (comma separated)
    Default: “”
  • Instance Type (string) : The type of instance that this cube needs to be run on
  • Memory (MiB) (decimal) : The minimum amount of memory in MiBs (1048576 B) this cube requires. Due to overhead, request a couple hundred MiB more than required.
    Default: 1800 Min: 256.0 Max: 8589934592
  • Metric Period (decimal) : How often to sample metrics, in seconds
    Default: 60 Min: 1 Max: 300
  • Remove Extended Ring Atoms (boolean) : When On, heuristics are used to reduce the size of the fragments by removing atoms from extended ring systems where possible. Turn Off to keep all atoms in complex ring systems. In very rare cases, (with obscure chemistries) turning this Off may reduce problems in fragmentation
    Default: True
  • Skip Conjugated Bonds (boolean) : If (On), skip conjugated single bonds (amides, esters, etc)
    Default: False
  • Simple Fragments Only (boolean) : Return only fragments with a single rotatable bond
    Default: False
  • Spot policy (string) : Control cube placement on spot market instances
    Default: Prohibited
    Choices: Allowed, Preferred, NotPreferred, Prohibited, Required

Field parameters

  • Extended Log Field (Field Type: StringVec) : Message extended log field
    Default: Extended Log Field
  • Input Molecule Field (Field Type: Chem.Mol) : Primary Molecule Field to use as input to the Cube
  • Log Field (Field Type: String) : Message log field
    Default: Log Field
  • Output Molecule Field (Field Type: Chem.Mol) : Primary Molecule Field to use as output to the Cube
  • Fragment Parent Molecule Field (Field Type: Chem.Mol) : Field for storing parent molecule with torsion atoms tagged.
    Default: Fragment Parent Molecule
