FreeBayes will provide VCF output on standard out describing SNPs, indels, and complex variants in samples in the input alignments. + +By default, FreeBayes will consider variants supported by at least 2 observations in a single sample (-C) and also by at least 20% of the reads from a single sample (-F). These settings are suitable to low to high depth sequencing in haploid and diploid samples, but users working with polyploid or pooled samples may wish to adjust them depending on the characteristics of their sequencing data. + +FreeBayes is capable of calling variant haplotypes shorter than a read length where multiple polymorphisms segregate on the same read. The maximum distance between polymorphisms phased in this way is determined by the --max-complex-gap, which defaults to 3bp. In practice, this can comfortably be set to half the read length. + +Ploidy may be set to any level (-p), but by default all samples are assumed to be diploid. FreeBayes can model per-sample and per-region variation in copy-number (-A) using a copy-number variation map. + +FreeBayes can act as a frequency-based pooled caller and describe variants and haplotypes in terms of observation frequency rather than called genotypes. To do so, use --pooled-continuous and set input filters to a suitable level. Allele observation counts will be described by AO and RO fields in the VCF output. + +------- + +**Galaxy-specific options** + +Galaxy allows six levels of control over FreeBayes options provided by **Choose parameter selection level** menu option. These are: + + 1. *Simple diploid calling*: The simples possible FreeBayes application. Equvalent of using FreeBayes with only a BAM input and no other parameter options. + 2. *Simple diploid calling with filtering and coverage*: Same as #1 plus two additional options: -0 (standard filters: --min-mapping-quality 30 --min-base-quality 20 --min-supporting-allele-qsum 0 --genotype-varinat-threshold 0) and --min-coverage. + 3. *Frequency-based pooled calling*: This is equivalent to using FreeBayes with the following options: --haplotype-length 0 --min-alternate-count 1 --min-alternate-fraction 0 --pooled-continuous --report-monomorphic. This is the best choice for calling varinats in mixtures such as viral, bacterial, or organellar genomes. + 4. *Frequency-based pooled calling with filtering and coverage*: Same as #3 but adds -0 and --min-coverage like in #2. + 5. *Complete list of all options*: Gives you full control by exposing all FreeBayes options as Galaxy widgets. + 6. *Input parameters on the command line*: Similar to the choice above but for those who does not like clicking. Here options can be directly typed into a text box. + +----- + +**FreeBayes options** + +.. class:: infomark + +Note that each Galaxy parameter widget corresponding to command line flags listed below: + +Input and output:: + + -t --targets FILE + Limit analysis to targets listed in the BED-format FILE. + -r --region chrom:start_position-end_position + Limit analysis to the specified region, 0-base coordinates, + end_position included.
