Rationale and background: 


GMAP is a tool for rapidly and accurately mapping and aligning cDNA sequences to genomic sequences.

  1. Inputs:
    1. Genome name: Name of the genome
    2. kmer: Size of the kmer that you want to use
    3. Genome fasta file (mandatory): Path to the genome fasta file
    4. gmapdb directory: Destination directory name

Test Data

Test data for this app appears directly in the Discovery Environment in the Data window under Community Data -> iplantcollaborative -> example_data -> gmap > test_inputs

Input File(s)


    1. Genome name: test_genome
    2. kmer: 15
    3. Genome fasta file (mandatory): genome.fa
    4. gmapdb directory: gmapdb

Output reports:

Expect a folder named gmapdb which you can use with gmap-2018.03.25 for mapping the reads against
