What are the different gene styles for?
With circular maps, there’s only one basic gene style (“Simple”), an arc with or without an arrow, although you can vary many aspects of the arc (presence, absence, direction of arrow; location of arc relative to plasmid backbone; color; text color; text position). Linear DNA maps are more likely to show genomic views, and so there are two additional gene styles available in Linear view: “Exons” and “Hybrid”. These styles are very similar to each other: Both show a gene as a series of exons (if the information is available). “Exons” style indicates the orientation of the gene by making the last exon an arrow; “Hybrid” style draws an arrow underneath or above the gene, to indicate the orientation. “Exons” view is a little less cluttered, but when the exons are small (e.g. when a long stretch of DNA is being mapped) the arrows are hard to see. “Simple” view makes gene location clearer. “Hybrid” view shows exons, and makes gene orientation easier to see, but also makes the view a little m
