WebOct 15, 2024 · I compared the chimeric alignments of STAR to the alignments of other fusion detection algorithms to find out, which reads STAR misses. I noticed that for paired-end data, STAR often fails to determine a chimeric alignment, if the mates overlap to a large extent (small insert size). This is a known issue that has been reported previously … WebSupport for chimeric alignment is future work. Simulation studies. Mason 0.1 was used to simulate reads from the GRCh37 major build of the human genome, including sex chromosomes, mitochondrial genome and ‘nonchromosomal’ sequences.

"WebMay 18, 2024 · The initial step of in circRNA detection is searching all chimeric alignments for “back-spliced” reads. These are reads for which two chimeric segments align on the same chromosome and strand, with the 5’ segment aligning downstream of the 3’ segment (Figure 1). By default, STARChip limits circRNA to chimeric alignments < " - Chimeric and circular alignments
