[maker-devel] Quick question about re-annotation

[Jason Stajich]

Well remember that ESTs are used as extra helper information to the ab
initio gene predictors so it will want to run all those predictions again
and re-call the gene structures from the combined output with this extra
info added in. So you will need to decide how you want these to be
incorporated and if you are willing to wait for the analysis to complete
again with this info. The pass through of the previous run will allow you
to keep the names from that previous run if they are important to you.
