Tajima d vcftools
Web6 nov 2015 · I noticed that the Tajima's D value returned was different from vcftools. I made the test again on a small example file by constructing a vcf format and its equivalent in fasta, and obtained a Tajima's D of 0.88 with vcftools, and a value of -0.065 in DNAsp (using the popgenome package in R, I obtained the same value as in DNAsp). Webvcf_calc.py: VCF Statistic Calculator Function ¶. vcf_calc.py: VCF Statistic Calculator Function. Automates the calculation of site/windowed fixation index (Fst), Tajima's D, nucleotide diversity (Pi), allele frequency, and heterozygosity using VCFTools. If no statistic is specified, windowed Fst is used by default.
