memexp.exe invert invert.def data.001 D0
where D0 is the normalization constant (equations 1, 2, 10, and 11). If D0 is set to zero, the program estimates this normalization constant from the data. Note that this automatic estimation is not recommended for data that have appreciable slope at short times when plotted versus log time. For such data, D0 should be set on the command line to a larger value and LAGMUL should be set to Chi2. Severely underestimating D0 can induce spurious maxima in f [10].
To analyze a MEM distribution output during the inversion, invoke MemExp with the command:
memexp.exe analysis analyze.def distribution.dat D0 output.err.dat
The fit derived from the the MEM distribution in the file distribution.dat is used to estimate standard errors that are included in the file output.err.dat.
