Description

D. ananassae PacBio reads generated by the Genome Institute at Washington University were aligned against the D. ananassae CAF1 genome assembly using BLASR. For each BLASR aligned read, we calculated the size of the unaligned region compared to the length of the entire read.

The color of the read in this track corresponds to its unaligned length

Methods

After constructing a bwt index for the D. ananassae CAF1 assembly, D. ananassae PacBio reads from 8 SMRT cells were aligned against the D. ananassae CAF1 assembly using BLASR with the following parameters:

  • minPctIdentity 70
  • bestn 1
