[maker-devel] Long introns from Augustus

Actually these are calls directly from Augustus (without using Maker).  They are not purely ab initio in that they are using hints from RNA-Seq data.

I had noticed that Maker does have some information about max intron length - does that mean it could be taken care of by Maker?  I don't have very good "EST" (transcriptome) assemblies because it is a very difficult organism to sequence.

Are these the ab intio calls that are merged or final MAKER models.
