Good afternoon,

I recently used OmniLog from BIOLOG for my experimentations : I tested the metabolism of different strains on 2 types of plates. I have 16 strains of 3 different groups (treatments) and when I analyse the data on OmniLog I don't know when and how to normalise the raw data : before or after calculating the parameters ? I would like to know if there's a significant difference on the metabolisation of a substrate between different groups but I don't know how to procede with this package.

Would you have any advice on how to treat this kind of data ?

Thanks !
