Run h12 genome-wide selection scan.

Parameters

contigstr

Reference genome contig name. See the contigs property for valid contig names.

window_sizeint

The size of windows (number of SNPs) used to calculate statistics within.

analysisstr, optional, default: ‘default’

Which haplotype phasing analysis to use. See the phasing_analysis_ids property for available values.

sample_querystr or None, optional

A pandas query string to be evaluated against the sample metadata, to select samples to be included in the returned data.

sample_setssequence of str or str or None, optional

List of sample sets and/or releases. Can also be a single sample set or release.

cohort_sizeint or None, optional

Randomly down-sample to this value if the number of samples in the cohort is greater. Raise an error if the number of samples is less than this value.

min_cohort_sizeint or None, optional, default: 15

Minimum cohort size. Raise an error if the number of samples is less than this value.

max_cohort_sizeint or None, optional, default: 50

Randomly down-sample to this value if the number of samples in the cohort is greater.

random_seedint, optional, default: 42

Random seed used for reproducible down-sampling.

Returns

xndarray

An array containing the window centre point genomic positions.

h12ndarray

An array with h12 statistic values for each window.
