BG3 Whole cell CIP-TAP 892_895 smallRNA RNA-seq alignment and analysis (Celniker project, Gingeras subgroup)


Libraries were created from small RNA (less than 200nt) isolated from D. melanogaster BG3 Whole cell CIP-TAP treated cell line extracts, sequenced using Illumina GAIIx with single-end modules, and aligned with NexAlign. Tracks show read alignments and density.
Total read count: 51570704
Mapped read count: 15347037
Alignment rate: 29%

General Description

The cap-enriched and 5' monophosphate D. melanogaster small RNA libraries were generated in biological duplicate. Each library was mapped independently using STAR (Gingeras Lab) to the dm3 assembly without U-extra. To further assess the data we constructed contigs from the merged biological replciates and calculated Reads per Million values for every exon annotated in Flybase 5.32 and Ginormous. Additionally, we assessed each element for reproducibility using a nonparametric irreproducible detection rate script (npIDR, Alex Dobin Gingeras lab).
