Mayday’s integrated R Terminal, RLink, has just been updated.

The new version fixes a bug where single columns of the expression matrix could not be accessed directly.

The new version is available for download. Please read the included how-to document for a quick installation guide.

We have now integrated our new extension, SeaSight, allowing users to import raw microarray data together with mapped sequencing reads.

Data from different platforms can now be integrated and analyzed together using Mayday’s wealth of methods for visualization, data-mining, classification, and statistics.

Mayday SeaSight offers methods for computing expression values from mapped reads, raw microarray data import, background correction, normalization and summarization and linking microarray probes to genomic coordinates. These transformations can be combined in a user-friendly graphical interface to quickly construct powerful normalization pipelines.

Click here to start Mayday (including SeaSight) with 512M of memory. You can also use our versions with 2GB or 6GB of memory, depending on your operating system.

Note that for more than 2G, you will need a 64bit version of Java. On some systems, you need to start Mayday twice to use the desired amount of memory, due to a limitation of the JVM. See the lower left corner of the Mayday window for a status of memory consumption.

We also prepared a small example dataset and a tutorial.

We now have a new integrated R terminal in Mayday: Mayday RLink

A presentation of RLink will be given in the course of the useR! 2009 conference.

You can have a look at the talk abstract. RLink is also available for download. Please read the included how-to document for a quick installation guide.

Please note that the current experimental build of the Mayday core is needed to use RLink.
