Formats lists of ISequenceRange or SequenceRangeGroupings into a file formatted in the BED format. Info for the specification of this format can be found at: http://genome.ucsc.edu/FAQ/FAQformat

Parses ISequenceRange objects that are formatted according to the BED format. This is a format of tab delimited text where the each line represents one range and each defines an ID, start and stop index. Info for the specification of this format can be found at: http://genome.ucsc.edu/FAQ/FAQformat In this format indices start their count from zero. The chromosome start index is inclusive and the chromosome end index is exclusive. There are three required fields in each line as described above. There are also 9 option fields. These are: name, score, strand, thickStartm thickEnd, itemRgb, blockCount, blockSizes, and blockStarts. This parser does not support the bigBED format.
