Greg, David, Lloyd - Thanks again for the guidance on Regrid and Map's interpolation functions. I'll take a closer look at the code and papers you have suggested; If I find additional references that might be useful for inclusion as a comment in the source (as per Richard's suggestio) I'll be sure to pass them on.
Best regards and thanks; Ken ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Kenneth Gage MD/PhD Student McGowan Institute for Regenerative Medicine & University of Pittsburgh Department of Chemical Engineering
