Estimating coverage in metagenomes

Nonpareil uses the redundancy of the reads in a metagenomic dataset to estimate the average coverage and predict the ammount of sequences that will be required to achieve "nearly complete coverage", defined as ≥95% or ≥99% average coverage.

You can use Nonpareil on-line (see an example) or stand-alone. If you use Nonpareil, please cite:
