Is Human_G1K_V37.Fasta Hg19?

Question

[Bioscientist]

Recently got humang1kv37.fasta file Just curious if this is hg19 sequence? Because hg19 is also called GRCh37. What does "g1k" mean?

If not, from where can I get the chromosome sequence for humang1kv37.fasta?

thanks

g1k = 1000 genomes

It is one version of hg19, but not the only one. From the linked page: "For the phase1 analysis we mapped to GRCh37. Our fasta file which can be found here called human_g1k_v37.fasta.gz, it contains the autosomes, X, Y and MT but no haplotype sequence or EBV"
