I have not been able to fit spectra in 5.2.24 even with the provided examples or my own old scripts that had previously worked. The fit window and plot of the experimental data seem normal, but the simulated spectrum has zero amplitude. When I change from fit to simulation using the starting parameters, the Pepper command simulates a reasonable spectrum.
Thanks,
Eric

Please update to the latest version, 5.2.25. This problem is fixed there.
