There is provided a computer system for visualizing and editing single molecule fragments and one or more previously-produced single molecule assemblies or "contigs." The present visualization and editing system allows a user to visualize large data sets resulting from single molecule map assembly operations, and to rapidly discern important features while errors and other discrepancies are conveniently resolved. The system includes one or more connectors connecting each to one or more databases capable of storing a diverse array of biomedical information, in addition to the single molecule data against which a user may validate the prior alignment and assembly. Embodiments described herein are thus useful in studies of macromolecules such as DNA, RNA, peptides and proteins. The visualization and editing system may be implemented and deployed over a computer network, and may be ergonomically optimized to facilitate user interaction.
