AMRFinderPlus v3.6.4
AMRFinderPlus v3.6.4 includes a significant rewrite of the mutation detection code to enable the detection of small indels and promoter mutations. This has necessitated a change in the database format.
In order to use the latest version of the AMRFinderPlus database (2020-01-06.1 at the time of release) you must upgrade to this version of the software.
Because this version is incompatible with AMRFinderPlus databases from previous versions, amrfinder -u must be run once this update is installed to get the latest version of the database.
