What’s the advantage of drawing a map from a plain text or FastA file?
GenBank and EMBOSS files describe genes and other features, but FastA and text sequences, by default, will be imported as a blank map of the appropriate size, as if you had just entered the size in Maps→New Linear DNA. The advantage is that you can map open reading frames and restriction enzymes on import. (Note that the sequence is not saved, so after the map is imported you can’t go back and find more restriction sites or open reading frames.
