Grinder 0.5.2

Tool for generating random amplicon and shotgun libraries
Grinder is a program that allows you to create artificial random shotgun and amplicon sequence libraries.

The libraries generated are based on reference sequences in a FASTA file. Grinder can produce metagenomes, pyrotag datasets or shotgun sequencing projects, which can be used to test the accuracy of bioinformatic tools or help decide between alternative sequencing methods in an experiment.

Main features:

  • arbitrary number of reads and read length distribution
  • simulation of various PCR and sequencing errors: chimeras, point mutations, homopolymers
  • random shotgun library or amplicon library (e.g. 16S)
  • support for creating paired-end shotgun datasets
  • specific rank-abundance or manually specified abundance for each genome
  • creation of independent datasets, that do not share any genomes
  • modeling of the bias created by different genome lengths
  • forbidden characters
  • alpha and beta diversity requirements
