We present a computer-aided method for determining nucleic acid secondary structure. The method utilizes a program which has the capability to filter matrix diagonal data on the basis of diagonal length, stabilization energy, and chemical and enzymatic data. The program also allows the user to assign selected regions of the structure as uniquely single-stranded or paired, and to filter out "trade-off" structures on the basis of such pairing. In order to demonstrate the utility of the program we present a preliminary secondary structure for the 3' end of alfalfa mosaic virus RNA 4 (AMV-4 RNA). This structure is based on an analysis which includes the use of in vitro partial enzymatic digestion of the RNA.
