Hi Nicolas,

Thank you very much for sharing your script for estimating the area per
lipid and explaining how you have done it. Eventhough I am not familiar
with python script, I am sure that your script will be very helpful. I will
try
to use it soon. Once again, thank you for your kindness.

Madhu
