Hi All, I was loading Arabidopsis ath1121501.db package using some old code to check my results from several years back. I got the following message: """ Warning: All Arabidopsis packages now require you to use the toggleProbes() method in order to expose multiple mappings. """ I googled and find in the AnnotationDbi document: """ In many probe packages, some probes are known to map to multiple genes. The reasons for this can be biological as happens in the arabidopsis packages, """ My question is: 1) What is happening biologically in the Arabidopsis package? 2) Does the warning message means that if I don't use "toggleProbes()" I only get probes that map to single gene? Is this true for other packages? Thanks, Song Li -- Postdoctoral Associate IGSP Duke University
