UMI Counting[edit]

Base Complexities[edit]

Knee Plots (5/19/2017)[edit]

Added from analysis performed yesterday (5/18). The knee plots show the UMIs, ordered by number of reads (descending), vs. total fraction of reads. Only the random UMI samples go up to 1 on the y axis, but that's because the others don't have 100% alignment.

Discussion[edit]

Sequencing results are good overall, at least good enough to move on to the BSA positive control and possibly cells for mRNA. Couple of notes:

  • Production run positive control yielded correct sequences
  • Samples had additional empty UMIs to theoretical Poissonian zero
  • Dephosphorylated had most (72%) empty UMIs
  • ThermoFisher had slightly better UMI complexity
  • The knee plots show that the dephosphorylated sample had the highest AUC, which is actually bad for this type of analysis
