Time(x-axis) vs performance parameters (y-axis) (cache memory in the top panel and CPU utilized in the bottom panel) during PVT run for single end read (SRR094775). This is the result using PVT in a standalone system with 16 GB onboard RAM and 8 cores (3.3 GHz) CPU. Numbers in bold below the arrows indicate the time span of execution of different steps of PVT: 1: filter_reads. 2: gene_align. 3: genome_align a: splitBy_chromReference. 4: find_juncs. b: concatenate_segments. 5: junc_align. 6: span_reads. 7: report.
