This directory contains gzip compressed GVF (Genome Variation Format) files: 

    canis_lupus_familiaris.gvf.gz 
        All germline variations from the current Ensembl release for this
        species
    canis_lupus_familiaris_structural_variations.gvf.gz
        All structural variations (if available for this species)
    canis_lupus_familiaris_failed.gvf.gz
        Any variations that have been failed by the Ensembl QC checks
    canis_lupus_familiaris_incl_consequences.gvf.gz
        All consequences of the variations on the Ensembl transcriptome,
        as called by the variation consequence pipeline

If available for this species, the file includes information on:
    - ancestral_allele
    - evidence
    - clinical_significance
    - global minor allele, frequency and count
Incl_consequences files include sift (if available for this species)
and polyphen (human only) predictions.

The data contained in these files is presented in GVF format, this is a
simple tab-delimited format derived from GFF3 which shows the location of
each variant along with the reference and variant sequences, an identifier
for the source of the data (typically a dbSNP rsID), and other relevant
information (e.g. genotypes, allele frequencies, the predicted effect of
this variant on a transcript), a short example is presented below. For
more details about GVF please refer to:

We use the sum command for calculating checksums.
