hi so, I think, in case of converting time scale to energy - this should be supported by beamline (beamline scientist) somehow... if there is any nonlinearity of the converion factor (Anatoly - what whould happened if D parameter is time/energy dependent?) I think only reference spectra can help - do you have it Syed? if you have all needed parameters the calibration can be relatively quickly done in some other programs, also in macro (for many files) but that's my speculations kicaj

Apparently (and Khalid or Anatoly should correct me if I am wrong), they are collecting data as a function of time in quick scan mode. They then have the problem of converting time to energy. If the mono speed is recorded somehow incorrectly, then there is an accordian effect throughout the data. I think that Khalid wants to be able to adjust this accordian effect to correct the energy scale of teh data.
