Visualization of nucleic acid sequence structural information

Several interactive Pascal programs have been written for the analysis and display of structural information in nucleic acid sequences. Layout procedures were developed to display the homology and repeat matrices of a sequence and to predict and display the secondary structure of RNA/DNA molecules free of overlap and to predict and display internal repeats. No special plotting devices are required because the output is adapted to line printers. Sequences from several DNA database systems can be used as input. These programs are part of a general nucleic acid sequence analysis package.
