Dec 11, 2020 · The resultant files were further processed with SAMtools (v0.1.18) and BCFtools (v0.1.17) to generate variant call format files. VCFtools (v0.1.16) [ 86 ] was used to filter out variants with low quality scores (Quality value < 100) and to compare samples pairwise to identify mutations unique to each suppressed strain.
The best tool for the job is probably bcftools as suggested by Bioathlete, but you can also do this manually. You just need to collect all header lines from all vcf files, remove any duplicates, and then print all the headers + the actual data into the new one:
Feb 12, 2020 · The VCFs with these variants were then normalized using bcftools norm (1.9) and combined with the SVs across samples using bayesTyperTools to produce the input candidate set. k-mers in the raw reads were counted using kmc (3.1.1) with a k-mer size of 55. A Bloom filter was constructed from these k-mers using bayesTyperTools makeBloom.
Bcftools isec question? (self.bioinformatics). submitted 1 year ago by tappyhappy1. Hello! I have multiple vcf files for different strains generated by calling them to a common reference.

Use the bcftools view or bcftools filter command to count the number of: a. SNPs b. homozygous variants SNPs b. homozygous variants Depth is also a common filtering characteristic that many people use to remove low confidence variants.
Chapter 22 Basic Handling of VCF files. As we saw in the section on bioinformatic formats, VCF files can be large and unwieldy. The format specification is also such that fields might have different numbers of subfields, depending, for example, on the number of alleles found at a variant.
