The new Create Local Big Data Environment node creates a fully functional local big data environment including Apache Spark, Apache Hive and HDFS. It allows you to try out the nodes of the KNIME Big Data Extensions without a Hadoop cluster.

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
