271 **What it does**
|
|
|
272
|
|
|
273 Grinder is a program to create random shotgun and amplicon sequence libraries
|
|
|
274 based on reference sequences in a FASTA file. Features include:
|
|
|
275
|
|
|
276 * shotgun library or amplicon library
|
|
|
277 * arbitrary read length distribution and number of reads
|
|
|
278 * simulation of PCR and sequencing errors (chimeras, point mutations, homopolymers)
|
|
|
279 * support for creating paired-end (mate pair) datasets
|
|
|
280 * specific rank-abundance settings or manually given abundance for each genome
|
|
|
281 * creation of datasets with a given richness (alpha diversity)
|
|
|
282 * independent datasets can share a variable number of genomes (beta diversity)
|
|
|
283 * modeling of the bias created by varying genome lengths or gene copy number
|
|
|
284 * profile mechanism to store preferred options
|
|
|
285 * API to automate the creation of a large number of simulated datasets
|
|
|
286
|
|
|
287
|
|
|
288 **Input**
|
|
|
289
|
|
|
290 A variety of FASTA databases containing genes or genomes can be used as input
|
|
|
291 for Grinder, such as the NCBI RefSeq collection (ftp://ftp.ncbi.nih.gov/refseq/release/microbial/),
|
|
