447 Output compressed BCF (b), or uncompressed VCF (v).
448 Use the BCF option when piping between bcftools subcommands to speed up
449 performance by removing unecessary compression/decompression
450 and VCF<->BCF conversion.
451
452 This Galaxy tool recommends using the compressed BCF format
453 as piping is not implemented, and uncompressed data would
454 use unnecessary amounts of space.

459 Region Selections
460 -----------------
461
462 Regions can be specified in a VCF,
463 BED, or tab-delimited file (the default). The columns of the
464 tab-delimited file are: CHROM, POS, and, optionally, POS_TO,
465 where positions are 1-based and inclusive. Uncompressed
466 files are stored in memory, while bgzip-compressed and
467 tabix-indexed region files are streamed. Note that sequence
468 names must match exactly, "chr20" is not the same as "20".
469 Also note that chromosome ordering in FILE will be
470 respected, the VCF will be processed in the order in which
471 chromosomes first appear in FILE. However, within
472 chromosomes, the VCF will always be processed in ascending
473 genomic coordinate order no matter what order they appear in
474 FILE. Note that overlapping regions in FILE can result in
475 duplicated out of order positions in the output. This option
476 requires indexed VCF/BCF files.

480 Targets
481 -------
482
483 Similar to regions, but the next position is accessed by streaming the whole
484 VCF/BCF rather than using the tbi/csi index. Both regions and targets options can be
485 applied simultaneously: regions uses the index to jump to a region and targets discards
486 positions which are not in the targets. Unlike regions, targets can be prefixed with
487 "^" to request logical complement. For example, "^X,Y,MT" indicates that
488 sequences X, Y and MT should be skipped. Yet another difference between the two
489 is that regions checks both start and end positions of indels, whereas targets checks
490 start positions only.
491
492 For the bcftools call command, with the option -C alleles, third column of the
493 targets file must be comma-separated list of alleles, starting with the
494 reference allele. Note that the file must be compressed and index. Such a file
495 can be easily created from a VCF using::
496
497 bcftools query -f'%CHROM\t%POS\t%REF,%ALT\n' file.vcf | bgzip -c > als.tsv.gz && tabix -s1 -b2 -e2 als.tsv.gz

507 Controls how to treat records with duplicate positions and defines compatible
508 records across multiple input files. Here by "compatible" we mean records which
509 should be considered as identical by the tools. For example, when performing
510 line intersections, the desire may be to consider as identical all sites with
511 matching positions (bcftools isec -c all), or only sites with matching variant
512 type (bcftools isec -c snps -c indels), or only sites with all alleles
513 identical (bcftools isec -c none).

517 | Flag value | Result |
518 +============+================================================================+
519 | none | only records with identical REF and ALT alleles are compatible |
520 +------------+----------------------------------------------------------------+
521 | some | only records where some subset of ALT alleles match are |
522 | | compatible |
523 +------------+----------------------------------------------------------------+
524 | all | all records are compatible, regardless of whether the ALT |
525 | | alleles match or not. In the case of records with the same |
526 | | position, only the first wil lbe considered and appear on |
527 | | output. |
528 +------------+----------------------------------------------------------------+
529 | snps | any SNP records are compatible, regardless of whether the ALT |
530 | | alleles match or not. For duplicate positions, only the first |
531 | | SNP record will be considered and appear on output. |
532 +------------+----------------------------------------------------------------+
533 | indels | all indel records are compatible, regardless of whether the |
534 | | REF and ALT alleles match or not. For duplicate positions, |
535 | | only the first indel record will be considered and appear on |
536 | | output. |

603
604 - "." to test missing values
605
606 ::

609
610 - missing genotypes can be matched regardless of phase and ploidy (".|.", "./.", ".") using this expression
611
612 ::
613
614 GT="."
615
616 - TYPE for variant type in REF,ALT columns (indel,snp,mnp,ref,other)
617
618 ::
619
620 TYPE="indel" | TYPE="snp"
621
622 - array subscripts, "*" for any field
623
624 ::
625
626 (DP4[0]+DP4[1])/(DP4[2]+DP4[3]) > 0.3
627 DP4[*] == 0
628 CSQ[*] ~ "missense_variant.*deleterious"

631
632 ::
633
634 MAX, MIN, AVG, SUM, STRLEN, ABS
635
636 - variables calculated on the fly if not present: number of alternate alleles; number of samples; count of alternate alleles; minor allele count (similar to AC but is always smaller than 0.5); frequency of alternate alleles (AF=AC/AN); frequency of minor alleles (MAF=MAC/AN); number of alleles in called genotypes
637
638 ::
639
640 N_ALT, N_SAMPLES, AC, MAC, AF, MAF, AN
641
642 **Notes:**
643
644 - String comparisons and regular expressions are case-insensitive
645 - If the subscript "*" is used in regular expression search, the whole field
646 is treated as one string. For example, the regex ``STR[*]~"B,C"`` will be
647 true for the string vector INFO/STR=AB,CD.
648 - Variables and function names are case-insensitive, but not tag names. For
649 example, "qual" can be used instead of "QUAL", "strlen()" instead of
650 "STRLEN()" , but not "dp" instead of "DP".
651
