View source: R/BlastN.R

Description

Takes a query genome and a BLAST database and tries to find hits for the query genome by slicing it up by a user defined quantity.

Usage

1
BlastN(query, db, slicesize=100, leaps=900)

Arguments

query

Path to the query genome file

db

Path to the database genome file (must already have been turned into a BLAST database via MakeDB)

slicesize

Length of each nucleotide sequence to BLAST against the database

leaps

Number of nucleotides to skip between each BLAST query

Details

Scans through the query genome, reading in a nucleotide sequence of length slicesize, then stores that sequence in an output file. Skips leaps number of nucleotides and then repeats until the end of the query genome is reached. The output file containing all the nucleotide sequences is then queried all at the same time against the database.

Value

Returns a number of data files (text files). These should not be altered by the user.
