Hi Babe_Ruth,

» However, when I set BQL to 0, it uses a linear-trapezoidal rule: (Clast + 0)*(T16 - Tlast)
well... let me try to cite it again :-D
If a start or end time falls within the range of the data but does not coincide with an observed data point, then a linear or logarithmic interpolation is done to estimate the corresponding Y, according to the AUC Calculation method selected in the NCA Options. (See “NCA Options tab” on page 42.) Note that logarithmic interpolation is overridden by linear interpolation in the case of a non-positive endpoint.
A question:
is 0 a positive endpoint?

PS: nice to see you are using good oldie 6.3 (decennary next year)

Kind regards,
Mittyri
