Bcftool

In general, whenever multiple VCFs are read simultaneously, they must be indexed and therefore also compressed. Note that files with non-standard index names can be accessed as e, bcftool. BCFtools is designed to bcftool on a stream.

I am trying to merge multiple VCF files using bcftools but it threw an error saying that the file is not compressed. Whether you should index your compressed vcf file or not, depends on what tool you like to run afterwards on that file. Some require it, some not. But the tools that don't need an index file, also doesn't make use of the advantage to have random access to the positions in the vcf file. There are two indexing format: tbi and csi.

In general, whenever multiple VCFs are read simultaneously, they must be indexed and therefore also compressed. Note that files with non-standard index names can be accessed as e. BCFtools is designed to work on a stream. It regards an input file "-" as the standard input stdin and outputs to the standard output stdout. Several commands can thus be combined with Unix pipes.

Note that if the command fails at this step because of too many open files, your system limit on the number of open files "ulimit" may need to be increased. The sample order is updated to reflect that given in the input file. Note that for querying FORMAT vectors, the colon ":" can be used to select a sample and an element of the vector, as shown in the examples below. Please download release tarballs from www. Loading publications See also --ploidy-file. For "vertical" merge take a look at bcftools concat or bcftools norm -m instead. In the case of records with the same position, only the first will be considered and appear on output. BAQ is the Phred-scaled probability of a read base being misaligned. Coefficient for modeling homopolymer errors.

In general, whenever multiple VCFs are read simultaneously, they must be indexed and therefore also compressed. BCFtools is designed to work on a stream.

Symbolic alleles are not supported. When multiple ALT alleles are present in the annotation file given as comma-separated list of alleles , at least one must match one of the alleles in the corresponding VCF record. The two may be used in conjunction. Settings applied are as follows:. Rules for merging vector tags at multiallelic sites. Thanks in advance. Make sure to use the -O u option when piping! Similarly, at least one alternate allele from a multi-allelic VCF record must be present in the annotation file. For example:. It regards an input file "-" as the standard input stdin and outputs to the standard output stdout. Further information. Note that -t cannot be used in combination with -T. With the --naive option, the files are concatenated without being recompressed, which is very fast.. Script for processing output of bcftools stats.
