My group at is hiring a PhD student to explore how fungal pathogens that live in the environment will adapt their genomes, acquire new phenotypes, and perhaps even increased infectivity as a result of climate change. Please share!

I agree, SIRIUS is a great tool and can be helpful for that task! You can also add your (expected) macrolide structures in SIRIUS, in case they are not in public databases yet.
