Before revision: We predict crucial inter-atomic interactions between monomers for the autonomous assembly of three icosahedral viral capsids , Adeno Associated Virus type 2 (AAV2) , Murine Parvo Virus (MVM),  and Bromo Mosaic Virus (BMV), by approximating changes in the partition function of the capsid assembly landscape when an interaction is removed. At the interface-scale, the partition function computation usesatlases of selected subassembly landscapes for each interface type and their abbreviated\emph{bar-codes .
After revision: We predict crucial inter-atomic interactions between monomers for the autonomous assembly of three icosahedral viral capsids , Adeno Associated Virus type 2 (AAV2) , Murine Parvo Virus (MVM), and Bromo Mosaic Virus (BMV), a T=3 single stranded RNA virus. Experimental validation is by site-directed mutagenesis data and biophysical assays. We combine predictions at two scales: at the interface-scale, the partition function computation usesatlases of selected subassembly landscapes for each interface type and their abbreviated\emph{bar-codes .
