Bio.SeqIO support for the “xdna” file format.
The Xdna binary format is generated by Christian Marck’s DNA Strider program and also used by Serial Cloner.
Parse a Xdna file and return a SeqRecord object.
Note that this is an “iterator” in name only since a Xdna file always contain a single sequence.
Write files in the Xdna format.
Write the specified record to a Xdna file.
Note that the function expects a list of records as per the SequenceWriter interface, but the list should contain only one record as the Xdna format is a mono-record format.
