Python genomic features extractor from raw files (Fasta, GTF and VCF).

*gfeat* is a convenient tool for extracting diverse DNA features for genomic modeling and analysis. It allows to get,
for example, transcript Kozak sequence and GC content, genome codon pair bias and etc. It is also possible to inject
SNPs using a VCF file, get position-type variant matrices and investigate sequences with different combinations
of heterozygous variants (when homozygous always stay injected in the sequence).

You can find several short usage examples in the Tutorial section of the documentation.
