Fig. 2: Effect of read depth on error rate.
From: Error correction enables use of Oxford Nanopore technology for reference-free transcriptome analysis

a shows the median error rate of the SIM-ca read experiment based on true read depth of the transcript (i.e. number of reads sequenced from it). b shows the median error rate of the SIRV data as a function of read depth, obtained via subsampling (see “Data analysis”). The shaded areas show the standard deviation (SD) of the error rates.
