Figure 2.

An example of a GVF annotation, showing three hypothetical sequence alterations: an SNV, a deletion and a duplication. Lines beginning with '##' specify file-wide pragmas that apply to all or a large portion of the file. Lines are broken over multiple lines and separated by empty lines for presentation in the manuscript, but all data for a given pragma or feature should be contained on one line in a GVF file. A description of the tag-value pairs is given in Table 1.
