Bioinformatic pipeline speed evaluation. The table shows the speeds of our bioinformatic pipeline for four different runs on a bam file having ~200 million 76 nt-long stranded RNA-seq paired-end reads aligned to the human genome (GRCh37). The number of SINEs having an expression coverage over the calculated background signal (column 3) arises from different ‘-bg’ parameters in column 1 (see text for details). The step in the pipeline for expression coverage vector creation from the supplied bam file took almost 2 h.
