Software Relax is the powerful tool both to utilize the standard NMR relaxation routines and to create new ideas of pulses, gradients, gains and attenuations in the way of any complexity. The built-in script language based on widespread Pascal syntax is enriched with commands of fitting, Fourier and Laplace transforms, Low-pass filtering. The script supports dialogue windows, static messages, user-defined diagrams, data manipulation procedures. Relax allows direct processing of spectra, that can turn the Spin Track into NMR spectrometer.
