Lots of variations in the ontology or descriptors that can be used in GFF3 which requires writing a custom parser to handle a GFF3 generated or used by a specific application. Probably could be abstracted out but for now easier to handle with custom code to deal with gff3 elements that are not included but can be extracted from other data elements.

Parameters:

fastaSequenceFile -

gffFile -

lazyloadsequences - If set to true then the fasta file will be parsed for accession id but sequences will be read from disk when needed to save memory

Returns:

Throws:

java.lang.Exception
