It is open-source software, released under a BSD 3-clause license.
The main components are: The Staden Package was developed by Rodger Staden's group at the Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge, England, since 1977.
[5] The package was converted to open-source in 2004, and several new versions have been released since.
During the years of active development, the Staden group published a number of widely used file formats and ideas, including the SCF file format,[6] the use of sequence quality scores to generate accurate consensus sequences,[7] and the ZTR file format.
