Bio::FeatureIO is an iterator subsystem for genomic sequence features.
|
|
|
|
Bio::FeatureIO is a handler module for the formats in the FeatureIO set (eg,
|
|
Bio::FeatureIO::GFF). It is the officially sanctioned way of getting at the
|
|
format objects, which most people should use.
|
|
|
|
The Bio::FeatureIO system can be thought of like biological file handles. They
|
|
are attached to filehandles with smart formatting rules (eg, GFF format, or BED
|
|
format) and can either read or write feature objects (Bio::SeqFeature objects,
|
|
or more correctly, Bio::FeatureHolderI implementing objects, of which
|
|
Bio::SeqFeature is one such object). If you want to know what to do with a
|
|
Bio::SeqFeatureI object, read Bio::SeqFeatureI.
|
|
|
|
The idea is that you request a stream object for a particular format. All the
|
|
stream objects have a notion of an internal file that is read from or written
|
|
to. A particular FeatureIO object instance is configured for either input or
|
|
output. A specific example of a stream object is the Bio::FeatureIO::gff object.
