The simulation of RNA-Seq in Saccharomyces cerevisiae joins a reverse transcription model by poly-dT primers with subsequent fragmenation by DNAseI. Sequence biases that have been reported for the DNAseI fragmentation process (Hansen et al. 2010) are captured in the simulation by a position weight matrix (DNAseI.pwm).
