OR you can type your data in the next area, or cut and paste it from another application. Add some extra explanatory information to the text output. Suboptimal exons, on the other hand, are defined as potential exons which have probability above a certian threshold but which are not contained in the optimal parse of the sequence.
Suboptimal exons have a variety of potential uses.
First, suboptimal exons sometimes correspond to real exons which were missed for whatever reason by the optimal parse of the sequence. The cutoff is the probability cutoff used to determine which potential exons qualify as suboptimal exons. This argument should be a number between 0.01 and 0.99. For most applications, a cutoff value of about 0.10 is recommended. Setting the value much lower than 0.10 will often lead to an explosion in the number of suboptimal exons, most of which will probably not be useful.
