Release Notes

v0.6.1 August 2020

General Notice

  • Upgrades to use OpenEye-Snowball==0.19.1 and the associated OpenEye-orionplatform

New Floes

  • New Classic Shapequery To Record Floe reads shape query from a file and outputs it to a dataset.
  • New Classic Spruce - OEDesignUnit Type Updater has been added to convert datasets containing design units in the old Blob type to the new Types.Chem.DesignUnit type, which is required if a user wants to visualize the design unit in the 3D viewer. The Floe retains the old Blob type for backwards compatibility for this release, and merely adds the new fields.

Floe Updates

  • Classic Spruce - Prep from PDB Codes and Classic Spruce - Prep from Files Floes now by default include loop modeling for gaps in protein structures. Preparation times are expected to increase, dependent on the number and lengths of the missing loops.
  • Classic Szybki Free Ligand Floe and Classic Szybki Activesite Ligand Floe no longer fail when the solvent model is set to PB.
  • The Classic BROOD Floe has been improved to align depictions of hits with the non-changing part of the BROOD query.
  • The Classic OMEGA Floe now supports ‘fix molecule’ and ‘fix smarts’ to fix an portion of the input molecule.
  • Support of Open FF 1.0 has been added to the following Floes. PARSLEY_OPENFF100, PARSLEY_OPENFF111 and PARSLEY_OPENFF120 are added as predefined choices, and an .offxml file that defines a SMIRNOFF force field can also be used as input.
    • Classic Szybki Activesite Ligand
    • Classic Szybki Free Ligand
    • Classic Szybki Ligand Hydrogen
    • Classic FreeForm Conformer Energies
    • Classic FreeForm Restriction Energies
  • The Classic ROCS Floe has been updated to suport a shape query as well as a query molecule.
  • The Classic Szybki Activesite Ligand Floe now assigns charges to proteins if they are not charged. The Floe used to fail if the protein is not charged.

Removed Floes

  • The Classic Spruce - OEDesignUnit Upload Floe has been removed, as Orion now automatically can ETL OEDU files to records.

v0.5.2 April 2020

General Notice

  • Upgrades to use OpenEye-Snowball==0.18.2 and the associated OpenEye-orionplatform

New Floes

  • The spruce Floes refactored into two new Floes, the old Floes have been removed. The refactor of the Floes has removed the need to run multiple Floes to prepare strutures for modeling, furthermore, the Floes now write a single dataset containing multiple design unit records. The Floe can take multiple files or PDB codes, e.g. it is possible to prepare all the structures for a given target in parallel providing a single optional reference to superpose all the structures to.

    • Classic Spruce - Prep from PDB Codes
    • Classic Spruce - Prep from Files

Floe Updates

  • Classic Posit has been improved to not always require high-memory machines.
  • Classic OEDocking now fails more cleanly on bad receptor input.
  • Classic Substructure Search now generates an additional output of un-matched compounds.

v0.4.0 November 2019

    • Classic FreeForm Conformer Energies: Floe for conformer free energies
    • Classic FreeForm Solvation Energies: Floe for solvation free energies

  • The Classic Omega Floe enhanced with an optional Maximum Number of Conformers parameter.
  • The Classic ROCS and Classic OEDocking Floes have been enhanced with a switch to turn on/off depiction of images.

v0.3.6 September 2019

General Notice

  • Upgrades to use OpenEye-orionplatform==1.1.4 and OpenEye-Snowball==0.16.6
  • The Classic Floes package is deployed in two parts: (1) OpenEye classic Floes: contains Floes that are robust and well behaved; (2) OpenEye classic Floes BETA: contains Floes that are functional but may be ill-behaved to some inputs. Floes from the BETA package would be moved to the standard package, as they are improved over time.

New Floes

  • A specialized Floe for generating single 3D structure from a 1D/2D molecule.
  • A Floe has been added to convert OEDesignUnits prepared outside of Orion to the format of output datasets produced by Classic Spruce Prep.
  • A set of Floes have been added to prepare Unprepped datasets required for input to Classic Spruce Prep.

Floe Updates

  • The Classic OMEGA Floe is now simplified to generate conformers for predefined use case based modes.
  • The Classic ROCS Floe now produces more focused result fields, and responds properly to the user choice of sorter type field to produce the hitlist.
  • The following Floes have been improved to better respond to bad inputs, and provide a comprehensive report on total or partial failure of the underlying jobs: * Classic Omega * Classic ROCS * Classic Docking * Classic Posit
  • The Classic SPRUCE Prep Floe has been simplified, with many input parameters removed in favor of a robust set of defaults. The primary input to the Classic Spruce Prep Floe is an Unprepped PDB/MTZ dataset. An Unprepped input dataset can be generated using one of the following following Floes also in Classic Spruce: * Classic Spruce: PDB Code * Classic Spruce: PDB Codes File * Classic Spruce: PDB File Each of these Floes produce Unprepped input datasets for Classic Spruce Prep, and require either an input PDB code, a text file of PDB codes, or an input PDB file respectively.
