The easiest way to find the alignment files you’re looking for is with the Data Portal. You can search for individuals, populations and data collections, and filter the files by data type and technologies. This will give you locations of the files, which you can use to download directly, or to export a list to use with a download manager.
You can find an index of our alignments in our alignment.index file. There are dated versions of these files and statistics surrounding each alignment release in the alignment_indicies directory. Please note with few exceptions we only keep the most recent QC passed alignment for each sample on the ftp site.
The reference assembly the 1000 Genomes Project has mapped sequence data to has changed over the course of the project.
For the pilot phase we mapped data to NCBI36. A copy of our reference fasta file can be found on the ftp site.
For the phase 1 and phase 3 analysis we mapped to GRCh37. Our fasta file which can be found on our ftp site called human_g1k_v37.fasta.gz, it contains the autosomes, X, Y and MT but no haplotype sequence or EBV.
Our most recent alignment release was mapped to GRCh38, this also contained decoy sequence, alternative haplotypes and EBV. It was mapped using an alt aware version of BWA-mem. The fasta files can be found on our ftp site.
