predictJunctions: Identify splice junctions

Description

Identify splice junctions from genomic RNA-seq read alignments.

Usage

predictJunctions(frag_exonic, frag_intron, min_junction_count, psi, min_anchor,
  retain_coverage)

Arguments

frag_exonic
IRangesList with exonic regions from alignments
frag_intron
IRangesList with introns implied by spliced alignments
min_junction_count
Minimum fragment count required for a splice junction to be included. If specified, argument alpha is ignored.
psi
Minimum splice frequency required for a splice junction to be included
min_anchor
Integer specifiying minimum anchor length
retain_coverage
Logical indicating whether coverage for each exon should be retained as an RleList in metadata column coverage. This allows filtering of features using more stringent criteria after the initial prediction.

Value

  • IRanges of splice junctions with metadata columns type and N, and optionally N_splicesite for retain_coverage = TRUE
