Genome Controls

Genome size Log-scaled from 1,000 bp to about 4 billion bp. Sequence complexity 0% means every position is the same base. 100% means A, C, G, and T are equally represented. Repetitive DNA This fraction is split into simple repeats and complex interspersed repeats.

Advanced repeat controls

Simple repeats within repeats The remainder is modeled as transposon-like and retrotransposon-like sequence. Simple repeat length Short tandem repeat unit length, from single-base repeats to 20 bp motifs. Complex repeat length Log-scaled from 100 bp to 10 kbp for transposon-like repeat units.
