Combine two different datasets of marker

Question

[LaFra]

Hi all,

I have a question: I used to different markers to characterize plants using the DNA matabarcoding technique. I analayzed the two datasets separately, but I would like to combine them in order to have a combined matrix of alla the species identified in each sample by each marker. I would like to use the relative abundances (not presence/absence), knowing that I have two different reactions (so I should take into account amplification and sequencing differences). Is it possible to do? if so, how? Do you have any references?

Thank you!
