public class GeneMarkGTFReader
extends Object

http://www.bioperl.org/wiki/GTF Read and write FeatureLists as GFF/GTF formatted files.

The GFF moniker is applied to a variety of tab-delimited formats that mock the notion of a standard. This class should parse most files bearing at least a passing resemblance to any of the formats. You will, however, need to research the semantics of the files you encounter. Generally, the format consists of 9 tab-delimited fields:

 seqname   source   featureType   start   end   score   strand   frame   attributes
 

The 9th field consists of key-value pairs separated by semicolons, the first of which JavaGene interprets as the group id (as used in GFF1). It is the precise meaning of this 9th field that varies from week to week. The Feature and FeatureList objects provide various utility methods to ease the task of accessing and using the attributes. The proper interpretation of any particular attribute, however, is left to you.
