Catalogue of Genetic Variation in P. falciparum - v6.0

Released on 13 Nov 2020.

Parasite

This page contains information about the Pf6 data release: data generated by the Plasmodium falciparum Community Project using the version 6 pipeline for variant discovery and genotype calling. This release contains sample information, accession numbers and genotype calls for samples as described in Plasmodium falciparum Community Project: about the version 6 data.

In 2018 the Plasmodium falciparum Community Project upgraded to version 6 of its variant discovery and genotype calling pipeline. Details of the methods can be found in the accompanying paper. The major change from previous versions is that the version 6 pipeline is based on GATK and utilises findings on genome accessibility generated by P. falciparum Genetic Crosses Project.

These data are available open access. Publications using these data should acknowledge and cite the source of the data using the following format: “This publication uses data from the MalariaGEN Plasmodium falciparum Community Project as described in ‘An open dataset of Plasmodium falciparum genome variation in 7,000 worldwide samples. MalariaGEN et al, Wellcome Open Research 2021642 DOI: 10.12688/wellcomeopenres.16168.1‘”.

This release contains details on contributing partner studies, sample metadata and key sample attributes inferred from genomic data, and genomic data including raw sequence reads. Further details and analytical results can be found in the accompanying data release paper: An open dataset of Plasmodium falciparum genome variation in 7,000 worldwide samples. MalariaGEN et al, Wellcome Open Research 2021642 DOI: 10.12688/wellcomeopenres.16168.1

A README file describes in fine detail all the files included in the release, the format and interpretation of each column, and contains some tips and tricks for accessing genotype data in VCF and zarr files.
