A Mathematica package (ALASKA) has been developed to simplify the measurement of protein folding kinetics by analysis of ^1H NMR lineshape analysis. This package reads NMR data in ASCII format and can simulate an aromatic ^1NMR spectrum with or without lineshape broadening from chemical exchange. We describe the analysis of a urea denaturation series of a fast-folding protein, the G46A/G48A variant of monomeric l repressor.
