Hi Alexey, you can use 'make compatible' function to adjust your spectra spacing to a target spectrum spacing.This works through interpolation. Alternatively if you are using the quant package, you can combine spectra with different spacings.You need to be aware though that the spacing of the first spectrum in your spectra list will be used as a grid for interpolating the rest of the spectra.

Dear colleagues, I want to compare the performance and, maybe, conduct a calibration transfer from one MPA spectrometer to other MPA spectrometer, which are identical. Looking on the raw spectra I found out those different copies of the same instrument have the different starting points: one is 12493.0 cm-1, and the other is 12493.3 cm-1. So, moving along the spectral range with a constant resolution, spectra from two identical instruments do not have common points. How I can set up these instruments to start with the same point? Is it possible, in principle? Of course, I can use OPUS software option �recalculate for equal scale�. But I don�t like this idea at all. Regards, Alexey |
