MedChem Wizard KNIME workflow


The MedChemWizard is a KNIME workflow designed to assist medicinal chemists with idea generation, ligand design and lead optimization using a number of common functional group transformations and medchem rules-of-thumb, this tutorial provided by Dr. Alastair Donald gives a detailed description of it's use.



Workflow tools


Workflow tools are becoming increasingly common in science and this publication by Wendy Warr gives an excellent comparison of the leading alternatives, Scientific workflow systems: Pipeline Pilot and KNIME DOI.

Really well worth a read.


KNIME 2.7 released

KNIME 2.7 has been released.

KNIME now runs on Java 7 for Windows and Linux systems (Mac stays on  Java 6) Eclipse update 3.7 increases stability on Mac and some Linux systems. BIRT 3.7 brings Open Office support among other new features

JFreeChart nodes have now more setting options in the “General Plot Options” tab of their configuration window.
In R-> Local there are a number of new nodes to import:

  1. “Table to R” can read a KNIME table into R and output the R workspace.  
  2. “R to Table” takes an R workspace and outputs a KNIME table.
  3. “R +Data to R” takes an R workspace and optional data input and outputs an R workspace.
  4. “R to R-View” takes an R workspace and outputs a KNIME view
