Need to extract specific VCF sample IDs from 1000Genomes project in the group 30x 1000 genomes genotypes aligned to gr38

Question

[screadore]

Hello everyone,

I'm trying to extract vcf files from a specific population sub-group in the 1000 Genomes project FTP.

I'm looking to get vcf files from 200 30X Whole Genome sequenced samples with American ancestry.

I then need to concatenate all of the chromosome VCF files together per sample. So the preferred output would be 1 VCF file per sample.

If anyone can assist me with doing this I would greatly appreciate it or offering alternative methods to get this done. Thank you!
