## DESCRIPTION: formatting a fasta format into phylip format for using with PAML

import string, os, sys
"""
if len(sys.argv) == 1:
    print "put arguments!!"
    print "USAGE: S01_phylip2fasta.py INPUT OUTPUT"
"""

## INPUT
if os.path.isfile(sys.argv[1]) :

## OUTPUT
f2 = sys.argv[2]
F2 = open("%s" %f2, 'w')
