This analysis can do any or all of these tree things:

Handle zero concentrations differently. Zero concentrations are sometimes a problem because the  logarithm of zero is not defined, so zero concentrations are lost in a log transform. With this analysis, you can specify that zero be substituted with a low value (say 10-9) before taking the logarithm.

Change units, for example from molar to nanomolar. Simply tell Prism what constant to multiply or divide by.

Transform to logarithms, often needed prior to fitting a curve.
