tRMA: tools for R Microarray Analysis

tRMA is a software package for the analysis of microarray images. It is available to selected research groups.

Its features include functions to

load certain types of (cDNA) microarray data files

examine the data through display and plot functions

normalise the data by removing biases within arrays

average data across slide and gene replicates

extract genes that are highly differentially expressed

cluster across genes or slides

tRMA is implemented as a suite of tools for the free data analysis environment, "R", and the user can therefore access all the graphical and statistical tools of R in addition to those provided by tRMA.

Note that the user must obtain R from the R Project home page(http://www.r-project.org/), for the purposes of using tRMA.

You can read the tRMA User's Guide here.

tRMA is currently being linked to a genomics array database, GENAdb.
