GVF-Parser A Lite parser for Genome Variation Format (GVF) files. GVF BACKGROUND The Genome Variation Format (GVF) is a very simple file format for describing sequence_alteration features at nucleotide resolution relative to a reference genome. The GVF format was published in Reese et al., Genome Biol., 2010;11(8):R88 GVF is a type of GFF3 file with additional pragmas and attributes specified. The GVF format has the same nine-column tab-delimited format as GFF3. All of the requirements and restrictions specified for GFF3 apply to the GVF specification as well and thus a GVF file should be fully compatible with code used for processing and displaying GFF3 files. In addition, GVF adds additional constraints to some of these columns as described via http://www.sequenceontology.org/resources/gvf.html GVF::Parser GVF::Parser partitions GVF files into pragma and feature data, and the feature data is further split into features and attributes. Pragma data is stored in object, and can be requested using the pragmaRequest method. Attribute information is stored/saved in a sqlite datafile, and can be accessed using the attributeRequest method, or more preferably via DBIx::Class requestset.
