**What it does**

Grinder is a program to create random shotgun and amplicon sequence libraries
based on reference sequences in a FASTA file. Features include:

  * shotgun library or amplicon library
  * arbitrary read length distribution and number of reads
  * simulation of PCR and sequencing errors (chimeras, point mutations, homopolymers)
  * support for creating paired-end (mate pair) datasets
  * specific rank-abundance settings or manually given abundance for each genome
  * creation of datasets with a given richness (alpha diversity)
  * independent datasets can share a variable number of genomes (beta diversity)
  * modeling of the bias created by varying genome lengths or gene copy number
  * profile mechanism to store preferred options
  * API to automate the creation of a large number of simulated datasets


**Input**

A variety of FASTA databases containing genes or genomes can be used as input
for Grinder, such as the NCBI RefSeq collection (ftp://ftp.ncbi.nih.gov/refseq/release/microbial/),
the GreenGenes 16S rRNA database (http://greengenes.lbl.gov/Download/Sequence_Data/Fasta_data_files/Isolated_named_strains_16S_aligned.fasta), theh uman genome and transcriptome (ftp://ftp.ncbi.nih.gov/refseq/H_sapiens/RefSeqGene/, ftp://ftp.ncbi.nih.gov/refseq/H_sapiens/mRNA_Prot/human.rna.fna.gz), ...

These input files can either be provided as a Galaxy dataset, or can be uploaded
by Galaxy users in their history.
 

**Output**

For each library requested, a first file contains the abundance of the species
in the simulated community created, e.g.::

  # rank  seqID                           rel. abundance
  1       86715_Lachnospiraceae           0.367936925098555 
  2       6439_Neisseria_polysaccharea    0.183968462549277 
  3       103712_Fusobacterium_nucleatum  0.122645641699518 
  4       103024_Frigoribacterium         0.0919842312746386 
  5       129066_Streptococcus_pyogenes   0.0735873850197109 
  6       106485_Pseudomonas_aeruginosa   0.0613228208497591 
  7       13824_Veillonella_criceti       0.0525624178712221 
  8       28044_Lactosphaera              0.0459921156373193 

The second file is a FASTA file containing shotgun or amplicon reads, e.g.::

  >1 reference=13824_Veillonella_criceti position=89-1088 strand=+
  ACCAACCTGCCCTTCAGAGGGGGATAACAACGGGAAACCGTTGCTAATACCGCGTACGAA
  TGGACTTCGGCATCGGAGTTCATTGAAAGGTGGCCTCTATTTATAAGCTATCGCTGAAGG
  AGGGGGTTGCGTCTGATTAGCTAGTTGGAGGGGTAATGGCCCACCAAGGCAA

  >2 reference=103712_Fusobacterium_nucleatum position=2-1001 strand=+
  TGAACGAAGAGTTTGATCCTGGCTCAGGATGAACGCTGACAGAATGCTTAACACATGCAA
  GTCAACTTGAATTTGGGTTTTTAACTTAGGTTTGGG

If you specify the quality score levels option, a third file representing the
quality scores of the reads is created::

  >1 reference=103712_Fusobacterium_nucleatum position=2-1001 strand=+
  30 30 30 10 30 30 ...
