readCount
β€’ large contribution from miRNA and mRNA
β€’ also some signal from exogenous sequences
total reads by biotype
exceRpt @ Genboree
β€’ extremely simple to use (1 input, 1 output)
β€’ can process multiple samples in parallel
β€’ very customisable (choice of smRNA libs, calibrators, etc)

input
output
β€’ exceRpt output from multiple samples can be combined,
compared, and tested for differential abundance
β€’ features:

- intuitive QC visualisations

- filtering & normalisation

- differential expression
β€’ processed expression data 

are excel, R, matlab, &

summary
β€’ trivial to use exceRpt thanks to:

- automated, linear workflow

- GUI, processing, & data/result storage on Genboree
β€’ average runtime for high quality RNA-seq sample:

- 1hr for endogenous-only analysis

- 2hr 30mins for endogenous+exogenous alignments
β€’ downstream network analysis tools directly integrated in
genboree and automatically accept exceRpt results

  • 25. summary β€’ trivial to use exceRpt thanks to:
 - automated, linear workflow
 - GUI, processing, & data/result storage on Genboree β€’ average runtime for high quality RNA-seq sample:
 - 1hr for endogenous-only analysis
 - 2hr 30mins for endogenous+exogenous alignments β€’ downstream network analysis tools directly integrated in genboree and automatically accept exceRpt results
