Description
The 2bit format is a binary format for efficiently storing (multiple) DNA sequences
in a compact randomly-accessible format (up to 4Gb). MotifLab is currently able to import DNA track data
from 2bit files, but is not able to output tracks in 2bit format.
More information about the 2bit format and how to create 2bit files
can be found
here
and
here.
2bit formatted files are often used to store entire genomes, and in this case
it is possible to extract DNA sequences for any segment as long as the
location is known. (In contrast with e.g. FASTA-formatted files where you can
only import DNA sequences if they have the same name and length as your
current sequence objects)
