Micro-Array integration

About Micro-Array Analysis

Much of this is driven by a desire to pull in users from the micro-array analysis community. Microarrays are a high throughput technique which is used to determine the level of expression (how much each gene in a genome is being transcribed, turned into protein products) at any given point. Typically raw data consists of a set of images in different states (control, diseased, mutant etc) and at different points in time - these images are analysed to obtain a time series of expression level per gene (many) per condition (fewer) per time point (again, many). Raw array data is big, it's not particle physics big but it's substantial enough to cause problems unless care is taken. The EBI provides the Expression Profiler tool, linked below, which performs some of this analysis - the bioconductor library is a set of R functions towards the same end.

Email list

An email list has been created, mygrid-array(.)listserv.manchester.ac.uk

The name tries to reflect the merging of mygrid and microarray research, but unfortunately "mygrid-microarray" was too long, so it's just array for now. Array! Array!

The purpose of this list is to discuss further progress in joining the technologies of MicroArray analysis with the myGrid framework, including Taverna, ExpressionProfiler^?, R, BioConductor^?, etc.
