POP is a little Program which derives probabilities of cis or trans conformation of Xaa-Pro peptide bonds based on the observed 13C chemical shifts.

POP was written by Dirk Labudde at the FMP in Berlin. It is a Tcl/Tk script and requires a Tcl/Tk version higher than 8.0

POP needs another file: Normalverteilung.dat with all statistical data
