WebInclude type strain sequences in your analysis to provide documented landmarks. Source: View only environmental (uncultured) sequences, only sequences from individual isolates, or both. Source classification is based on sequence annotation and the NCBI taxonomy. Size: View only near-full-length sequences ( > 1200 bases), short partials, or both. WebSum of lengths of the M/I/S/=/X operations shall equal the length of SEQ. This lets us trivially calculate the length of a sequence from its CIGAR by adding up the lengths of all the "consumes query" ops in the CIGAR.

Websequence strings are always full length, but colorspace quality strings can be truncated when CIGAR data indicates gaps or trimming. A temporary fix is to ignore the CIGAR alignment details in calculating the nt-quality string and just do it for the whole read.
