The Phase 1 integrated variant set does not report the depth of coverage for each individual at each site. We instead report genotype likelihoods and dosage. If you would like to see depth of coverage numbers you will need to calculate them directly.
The bedtools suite provides a method to do this.
genomeCoverageBed is a tool which can provide a bed file which specifies coverage for every base in the genome and intersectBed which will provide an intersection between two vcf/bed/bam files.
These commands also require samtools, tabix and vcftools to be installed.
An example set of commands would be:
samtools view -b ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/data/HG01375/alignment/HG01375.mapped.ILLUMINA.bwa.CLM.low_coverage.20120522.bam 2:1,000,000-2,000,000 | genomeCoverageBed -ibam stdin -bg > coverage.bg
This command gives you a bedgraph file of the coverage of the HG01375 bam between 2:1,000,000-2,000,000:
tabix -h http://ftp.1000genomes.ebi.ac.uk/vol1/ftp/phase1/analysis_results/integrated_call_sets/ALL.chr2.integrated_phase1_v3.20101123.snps_indels_svs.genotypes.vcf.gz 2:1,000,000-2,000,000 | vcf-subset -c HG01375 | bgzip -c > HG01375.vcf.gz
This command gives you the vcf file for 2:1,000,000-2,000,000 with just the genotypes for HG01375.
To get the coverage for all those sites you would use:
intersectBed -a HG01375.vcf.gz -b coverage.bg -wb > depth_numbers.vcf
