A very useful function in IGB for comparing splice variation, exon length, read location, etc. is Edge Matching. This function highlights ALL features that share the same start points, and/or the same endpoints. Simply select the item of interest, and IGB will highlight all matching edges (in all tracks within the Main View window) in white (by default). You can change the Edge Match color to one of your choice, so that it is visible on all background colors, as described in Other Options tabTab. You can also turn off Edge Match if it is interfering with creating a journal quality picture.
