VERSION

Version 1.0.1

DESCRIPTION

Bio::Sampling::Valection - Sampler for verification

Bio::Sampling::Valection contains a variety of algorithms for choosing verification candidates from competing tools or parameterizations, to fairly assess their performance against each other.

Originally created to selected from single nucleotide variant (SNV) calls generated by SNV mutation calling algorithms, this software can easily be extended to other mutation types (e.g. structural variants, gene fusions, etc.) provided data is formatted correctly.

This software requires the valection package (http://labs.oicr.on.ca/boutros-lab/software/valection).

SYNOPSIS

There are six selection methods available through six functions. They all take the following arguments:

- **budget**: an integer specifying how many candidates to select

- **infile**: a path to a file which contains the calls from all callers. The infile should be formatted with a tab separating the caller and call on each line:

caller1 name\ta call this caller made
caller2 name\ta call this caller made

e.g.

magnifying glass	chr1 576834
magnifying glass	chr1 6878924
eye dropper	chr1 496267
eye dropper	chr1 6878924

Note that the call can contain a tab, but the caller may not.

- **outfile**: a path to a filename where the calls should be outputted

- **seed** (optional): an integer to seed the random number generator with (used to randomize sampling)

use Bio::Sampling::Valection;

# Run the sampling to select 10 candidates
run_equal_per_caller(10, "/home/me/calls.valec", "/home/me/selections.txt", 50);

FUNCTIONS

The functions are named as follows:

run_directed_sampling

run_random_sampling

run_equal_per_caller

run_equal_per_overlap

run_increasing_with_overlap

run_decreasing_with_overlap
