If your study or research involves preparation of circular plasmid maps, you will find MacPlasmap an indispensable tool to have. It draws, stores, and prints high-quality circular plasmid maps with the data you specify. If you have not done this on a Macintosh computer before, MacPlasmap will convince you it is time to do so. Or if you have tried to draw plasmid maps with any of the popular Macintosh drawing programs, you may have been aware of the following inherent difficulties: Precise positioning of restriction sites and genes on a circle. Attaching an arc (representing a gene) onto a circle. Drawing maps of different sizes based on related, previous maps. Converting one type of map to a different type. MacPlasmap is designed to overcome all of the above while still retaining other essential features of a drawing program. As a stand-alone Macintosh application, MacPlasmap supports such common facilities as data entry, saving, retrieving, and printing. If necessary, plasmid maps produced by MacPlasmap can be transferred to other advanced drawing programs for modification. Consequently, you can use MacPlasmap both as a plasmid data organizer and a plasmid drawing aid.
