AltAnalyze is an easy-to-use application for microarry and RNA-Seq analysis. For splicing sensitive platforms, AltAnalyze will assess alternative exon expression along protein isoforms, domain composition and microRNA targeting. In addition to splicing-sensitive platforms, AltAnalyze provides comprehensive methods for conventional arrays (RMA summarization, QC, statistics, annotation, clustering, lineage characterization and gene-set enrichement). Registration not required.
