%% This suite allows AFM probe characterisation data to be imported and processed.
% Sets of data files pertaining to probe resonant frequency, deflection
% sensitivity, thermal tune spectra... ADD MORE IN TIME... may be
% systematically imported and processed to output values for spring
% constant and effective mass, along with ranges and error values. In each
% case, one or more .txt data files may be input. Measurement scale should
% be in the first column and intensity data in the second. More than 2
% columns of data is ok, additional columns will (currently...) be ignored.

% Tapping-mode cantilver tuning data. The first column should be
% frequency data, the second column should be intensitiy.

% Contact-mode force-distance spectra. The first column
% should be z movement, the second column should be deflection intensity.

% Contact-mode thermal tune data. The first column should be frequency
% data, the second column should be intensity. Requires value of deflection
% sensitivity used by software when aquiring data.
