Hello, *Bug:* Although the [Natural log] box was checked, the natural log was not being applied to the data (figure 1). This was very easy to miss. Data imported under the conditions of figure 1 (Purple) resulted in a deviation from Bruce Ravel’s Au foil (Blue), the original March import (Green), and the June import after ensuring the μ(E) box contained the natural log of (mkxpq.i0)/(mkxpq.i1) (Red) – Figure 2. *Replication of the bug:* The bug only appears if the following steps are followed: 1) In a new file X, fluorescence data is imported, i.e. natural log box is unchecked. 2) File X is saved and Athena is closed. 3) Athena is started and File X is opened. 4) When importing a new dataset, the natural log box will be checked but the natural log will not be applied to μ(E). *Solution:* 1) Uncheck and then check the natural log box.
