Calculates match or mismatch delta G (Kcal/mole), Tm (degrees Celsius), delta S and delta H for DNA-DNA hybrids with parameters from SantaLucia, PNAS 17 Feb 1998 . Input consists of one oligo per line, or two of equal length separated by a / for a mismatch. For example, ATGATTCAAAGACAG/CTGTCTATGAATCAT has an A-A mismatch. Mismatch must be at least four bases in. Multiple mismatches are OK, but each must be one base long.
