Introduction

ArrayAnalysis.org is an open source, free to use online platform for analysis of microarray data - and an alternative program for Chipster (tutorial also available). ArrayAnalysis is a webtool, so there is no need for download or access code, and it provides more extensive quality control than Chipster but it is limited to two microarray formats: Affymetrix and Illumina. The exact microarray type (e.g. Affy-1) is automatically recognised. This tutorial shows how to use the Affymetrix quality control (affyQC) module which is designed for doing quality control and preprocessing of microarray data from Affymetrix microchips. All source code has been written in R and is open-source, available under the Apache License version 2.0. It is available on our Download page.
