GCWIND: a microcomputer program for identifying open reading frames according to codon positional G + C content

GCWIND is a microcomputer (IBM-PC compatible) program for theidentification of protein-coding open reading frames. The programis similar to the FRAME program, but the latter has only beenimplemented for a specialized graphics package. The base compositions(%G+C)for each of the three possible reading phases throughthe DNA sequence are displayed separately, together with thepositions of potential translation initiation and terminationcodons (on the leading and complementary strands), to providean immediate representation of those regions within the sequencethat have coding potential.
