Hi,

how do you predict operons in bacterial genomes from microarrays?

So far, I have found these databases:

DOOR2 RegulonDB ProOpDB OperonDB PRODORIC OperomeDB MicrobesOnline

They use mostly the same general methods via gene distance, STRING, conservation across genomes etc., but would it be possible to infer operon existence via microarray datasets only? Can you recommend some interesting algorithms that I can implement in my research?

Some of the above tools, such as Microbes Online, do use transcriptome datasets, but the last update was in 2011.

Could you please help me with this issue at hand?
