Psi4 Assign Constraints

This Cube finds atoms with the specified ‘atom_tag’ and then generates a constraint for a Psi4 optimization. Currently we only support two options:

  • 2 tagged atoms can be used in a distance constraint

  • 4 tagged atoms which are bonded in a row are assigned a torsion angle constraint

If the tagged atoms do not meet one of these options, then the record is sent to the failure port.

Calculation Parameters

  • Atom Tag String (string) : Tag for the atoms in torsion

    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
  • 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
