Headers
This text describes the fields in the example file (and most files
coming out of genomecomb analysis) shortly. More detail on the format
of the example files can be found in format_tsv.
Some of the fields apply to variant itself: the basic variant
fields describe the variant itself, the annotation fields give info
on the variant (location etc.).
Sample specific fields are given separately for each sample by
appending a dash and the sample name to the generic fieldname. They
specify data about the variant that can be different for each sample,
e.g. the genotype (a sample can have a reference, heterozygous,...
genotype for the variant), or sequencing quality score.
Basic variant fields
- chromosome: chromosome number
- begin: start position of variant (zero based)
- end: end position of variant (zero based)
- type: single nucleotide variants (snp), short
insertions (ins), deletions (del) or substitutions (sub), or the
combinations of two different variant types at heterozygous
positions (e.g. del_snp).
- ref: The reference allele at this position
- alt: The alternative allele at this position
