rQuant: quantitative detection of alternative transcripts with RNA-Seq data
High-throughput sequencing technologies open exciting new approaches to transcriptome profiling. For the important task of inferring transcript abundances from RNA-Seq data, we developed a new technique, called rQuant, based on quadratic programming. Our method estimates biases introduced by experimental settings and is thus a powerful tool to reveal and quantify novel (alternative) transcripts.
SoftwareThe source code of rQuant is available at our FTP server. It also contains code for an installation in the Galaxy framework. Please also check out our web service rQuant.web.
