Feature Ring

Miscellaneous features can appear on the interior ring or on one of up 10 middle rings. To specify the inner ring use the character I, otherwise give a ring number between 0 and 9. By default only the inner ring is drawn--if no ring information is entered all features appear here. If at least one ring number is entered in this field middle rings are drawn. Note that the specified ring numbers are relative: only rings where an actual feature is entered will be drawn. Thus if you enter features on rings 1,3 and 6, there will be three rings ordered (from inside to out) 1,3,6. These rings can be used to indicate, for instance, the location of clones from a sequencing project. If ring information is given, the number of Is and #s must match the total number of features.
