Raman spectra can be imported into the software in all common data formats, such as TXT, CSV, LPE or SPC files. In the first step after the data import, a number of different pre-processing steps are carried out to standardise the spectra. These include:

Cosmic ray peak correction;
Wavenumber calibration;
baseline correction;
spectral normalisation.

Advanced users have access to a wide range of manually adjustable pre-processing parameters and individual data quality filters. Here it is possible to set thresholds for the following values:

selected quality peaks (min and max);
correlation with the mean spectrum;
signal-to-noise ratio (min);
background intensity (max);
integrated intensity of baseline-corrected spectra (min and max).

Individual data processing steps can be monitored by recording the mean spectra at each step.
