Updated INSTALL and README links. for BASE

This package contains two plug-ins for BASE: RMAExpress and Plier.

RMAExpress and Plier are two similar plug-ins needed to make use of Affymetrix data in BASE. Affymetrix data can be imported into BASE as files, but if one wants to perform clustering and other analysis available in BASE, the data in these files have to be extracted and imported into BASE.

These plug-ins do not implement the RMA method and Plier method, but rather relies on third-party binary packages.

The RMAExpress plug-in relies on RMAExpressConsole available in the RMAExpress package available at The RMA algorithm is published in scientific journals, for more information please refer to the RMAExpress web site. In short RMA is the Robust Multichip Average. It consists of three steps: a background adjustment, quantile normalization, and finally a summarization.

The Plier plug-in relies on apt-probeset-summarize included in Affymetrix Power Tools (APT) available at apt-probeset-summarize provides several methods (see Affymetrix home page). Here we use the method given with option flag `--option plier-mm`. For more information regarding the Plier algorithm please refer to the Affymetrix home page.


INSTALL describes how to install the plug-in (either from a (semi)pre-compiled package or the subversion repository).

README contains general information about the plug-in and hints on how to use it.

Information about the underlying algorithms can be found at and affymetrix homepage, respectively.
