Consistency tests for data acquired at different magnetic fields.
These three tests are used to assess the consistency of datasets
aquired at different magnetic fields. Inconsistency can affect extracted
information from experimental data and can be caused by variations in
temperature, concentration, pH, water suppression, etc.
This code calculates three functions for each residue. When comparing
datasets from different magnetic field, the value should be the same for
each function as these are field independent. The J(0) function is the
spectral density at the zero frequency and is obtained using a reduced
spectral density approach. The F_eta and F_R2 functions are the
consistency functions proposed by Fushman D. et al. (1998) JACS, 120:
10947-10952.
To assess the consistency of its datasets, one should first calculate
those values (J(0), F_eta and F_R2) for each field. Then, the user should
compare values obtained for different magnetic fields. Comparisons could
proceed using correlation plots and histograms, and the user could also
calculate correlation, skewness and kurtosis coefficients.
