[default] [2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length) [3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length) [4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX [5] site name = sample name [6] site name entered in site_name column in the orient.txt format input file -- NOT CURRENTLY SUPPORTED [7-Z] [XXX]YYY: XXX is site designation with Z characters from samples XXXYYY NB: all others you will have to either customize your self or e-mail ltauxe@ucsd.edu for help. OUTPUT output saved in samples will overwrite any existing files """
