The CLS values for the calculated 2D spectra and the FFCF Gaussian approximation.Calculated 1D and 2D spectra based on the calculated FFCF.Error propagation of FFCF parameters from CLS parameter covariance.Calculation of the FFCF parameters from CLS decay parameters.Additional MATLAB software files are available upon request. The CAFE GUI is presently only available for Windows 64-bit operating systems and requires installation of the free MATLAB Runtime Environment (MRE) v.

(GUI Only) Added table font size selection.Added automatic error correction algorithm for 'Calculated linewidth exceeds experimental FWHM' error.CAFE is currently freely available in two forms: a complete standalone GUI-based programĪnd a core MATLAB library that can be run from the MATLAB command line or integrated into other MATLAB software.

The program uses the theoretical relationships between the CLS and FFCF as well asĪrtificial neural networks (ANNs) to quickly and accurately calculate the parameterized FFCF from a parameterized CLS decay and linear absorption spectrum.Ĭomplete details of the underlying algorithm can be found in the associated publication and SI documents ( 1 (PDF) | 2 (XLSX) ). Time-correlation function, the Frequency-Frequency Correlation Function. CAFE is software used to process the results of the Center Line Slope (CLS) analysis that is used as an observable of spectral diffusion in 2D correlation spectroscopy to obtain the underlying
