[Homer-users] Baseline for concentration plots

[Mark William Boyer]

Hello,

I am fairly new to HOMER and was hoping to better understand how the y-scale and 'zero' is set for the concentration plots.  Specifically, I understand the meaning of the y-axis scales for the raw signal and OD plots, but I wanted to know exactly what the concentration scale indicates and how the zero value is set.

I've attached a diagram that hopefully provides some context to the question.  I could not find a definite answer in the documentation, so any insights into this would be much appreciated.

Thank you,
