From the developer:
PeakFit uses three procedures to automatically place hidden peaks; while each is a strong solution, one method may work better with some data sets than the others.
The Residuals procedure initially places peaks by finding local maxima in a smoothed data stream. Hidden peaks are then optionally added where peaks in the residuals occur.
You may want to check out more software, such as DeadLine, ChaosPro or Equation Wizard, which might be similar to PeakFit.
