Thanks to Pascal Mercier who did an extensive test of stc 4.2 and provided many helpful suggestions. Thanks to Fred Richards and T.J.Richmond, whose accessible surface area fortran software is still used in stc. William Wilcox also did modifications on the addradii subroutine. The work of K.P. Murphy and E. Freire forms the basis for the thermodynamics programming section. Thermodynamics of structural stability and cooperative folding behavior in proteins. Adv Protein Chem. 1992;43:313-61.
