Installation

Supported KNIME Analytics Platform versions: 4.6.x , newer versions probably as well

  1. In your KNIME Analytics Platform, select the menu point "Help" -> "Install new software.."
  2. add the following software repository: https://actelion.github.io/openchemlib-knime/update_site
  3. select the OpenChemLib Knime nodes for installation.

Getting started

Please check the file ./ExampleWorkflows/oclnodes-validation.knar It contains a couple of workflows that show the basic usage for some of the nodes nodes: (there is currently a bug in the reader node, such that you have to pick the correct input file manually. This will be fixed soon..)

  • ValidationWorkflow_Descriptors_01 : illustrates .dwar file loading, descriptor calculation and similarity calculation

  • ValidationWorkflow_Descriptors_02 : illustrates .dwar file loading, and multiple similarity calculation

  • ValidationWorkflow_IO_01 : illustrates .dwar file loading and saving

  • ValidationWorkflow_Sketcher_01 : illustrates usage of the the OCL sketcher and file saving

  • ValidationWorkflow_3D_01 : illustrates conformer generation, forcefield minimization, and PheSA-based 3D similarity computation

  • ValidationWorkflow_3D_02 : illustrates ligand pose import via SDF file and PheSA-based 3D similarity computation

  • ValidationWorkflow_DiverseSelection_01 : illustrates ultra-fast diverse selection algoritm (works only for binary fingerprints)

  • ValidationWorkflow_ClusterMolecules_01 : illustrates clustering based on descriptor-based similarity

  • ValidationWorkflow_ScaffoldAnalysis : illustrates computation of scaffolds and scaffold statistics
