Hi, I am trying to use the vcftools to get some summary statistics about my VCF file. When I was using the following functions:

zcat my.sorted.vcf.gz | vcftools --vcf - --het --out het
zcat my.sorted.vcf.gz | vcftools --vcf - --TajimaD 20 --out TajimaD

The tool did not give out any results but a blank sheet. Here is the message from the screen printout about TajimaD, but the heterozygosity displayed the similar message. My vcf file is not annotated. Do you think thats why it showed "CONTIG declaration found without ID: /A" ? Or it is because of something else, and what else could cause this? Thank you very much !

VCFtools - v0.1.12

    --vcf [stdin]
    --out TajimaD.out

Did you check the TajimaD.out file? By the way, you don't need to zcat the file manually, you can use the --gzvcf option to read it directly.

Thank you, Giovanni, I did check the out file. It is an empty doc with a header "CHROM BIN_START N_SNPS TajimaD"
