This is showing a comparison of the VCF file from the original SNP discovery analysis for one dataset, and a second run of the SNP discovery pipeline on the same dataset, but with technical replicates removed (blue). Version 1.14-20220112 source and binaries (for BCFtools 1.14 but HTSlib must be patched for bug 1362) Version 1.13-20211015 source and binaries (for BCFtools 1.13) Version 1.11-20210514 source and binaries (for BCFtools 1.11) Version 1.11-20210315 source and binaries (for BCFtools 1.11) Version 1.11-20210120 source and binaries (for BCFtools 1. Personally, I can validate this by saying that I recently ran vcf-compare and bcftools isec (as per above) and used the results to generate a Venn diagram with jvenn, shown below: Once you had the output of running these programs in hand, it would then be possible to do a number of things, such as report common/different SNPs between runs or treatments, conduct statistical anlaysis, or create a Venn diagram of common/different SNPs between multiple VCF files to visualize the differences.
#BCFTOOLS INSTALL MAC#
On mac or Linux with bcftools installed, you could use something like the following (where $ is the command line prompt) to get the list of SNPs at the intersection of two or more VCF files: $ bcftools isec -n +2 | bgzip -c > isec_file1-v-2_Īlternatively, if you wanted just statistics on the numbers of SNPs/variants or genotypes in common between files, you could use the vcf-compare tool that comes with vcftools. The program is intended to replace the Perl-based tools from vcftools. To mention other options, bcftools is supposedly faster at this, and if you use bcftools what you want is the intersection function, isec. BCFtools implements utilities for variant calling (in conjunction with SAMtools) and manipulating VCF and BCF files. The output file has the suffix “.diff.sites_in_files”.” “Outputs the sites that are common / unique to each file.

The Service has installed several data bases, contact the technicians to use them or install new ones. (Note: As of v2.3, we have augmented these maps with chrX, and we have also added a linear map geneticmap1cMperMb.txt for use with non-human data. Samtools and BCFtools both use HTSlib internally. This option for the -diff flag is listed in the documentation as having the following function: selecting the build (hg17, hg18, or hg19) corresponding to the base pair coordinates of your bim file.

from different SNP discovery pipelines, or two treatments of an experiment)?”, you might ask.īelow, I provide a post based on my recent answer to this ResearchGate question that provides some solutions for this problem.įirst, the vcftools -diff -diff-site option would work for this specific case. Consequence predictions are changed for 501 of 5019 compound variants found in the 81.7M variants in the 1000 Genomes Project data, with an average of 139 compound variants per haplotype.

“What are the SNPs or variants that are shared in common between two VCF files I created (e.g. BCFtools/csq is a fast program for haplotype-aware consequence calling which can take into account known phase.
