Comment: C: Getting allele frequency and zygosity information from several vcf file
... Hi Kevin, Many thanks for your kind message. I'm going to use GATK for this purpose, however, as I mentioned before, this tool doesn't tell us which samples are homo and which are hetero, unlike your script. So, I'm happy if you please let me know when you modify your script. Kind regards, Seta ...

Comment: C: Getting allele frequency and zygosity information from several vcf file
... Thank you, Kevin for your explanation and link. so, the multi-allelic site has a long story. However, as I mentioned the gatk (variants to table) correctly computed hetero and homo at these positions, however, this tool doesn't say which samples are homo and which are hetero, it may be a good idea t ...

Comment: C: Getting allele frequency and zygosity information from several vcf file
... Thanks Kevin, of course, I know it. so sorry, My question is: we have not any ref allele in the real (original) vcf file (all calls are as 1|2, 2|1 and 2/2). So, how it is generated in the normalized vcf file during splitting and counted by your script, what information used for calling this homRef ...

Comment: C: Getting allele frequency and zygosity information from several vcf file
... No problem. I also try to get this information from gatk (variants to table function), and it returned me 2 AltHet and 1AltHom, like what we can see in the vcf file (original vcf file). Yes, your script is correct based on normalized vcf file. however, I'm confused with real (original) vcf file as h ...

Comment: C: Getting allele frequency and zygosity information from several vcf file
... Hi Kevin, Thank you so much for your helpful response. First, I normalized vcf file by bcftools norm –m-any and tried your command on the very small vcf file containing just 3 samples and found a strange thing. One of rows in my vcf file is: 20 1110696 rs6040355 A G,T 67 PASS NS=2;DP=10;AF=0. ...

... Dear all, I have multiple vcf file and want to extract allele frequency and the hetero- and homozygous call with their count. Could you please let me know if I should merge all vcf file to get one vcf file, and then extract the required information? If yes, I read CombineVariants from GATK do this ...
