[maker-devel] ab-initio gene-prediction

Dear Carson,

That is correct. There were no pred_gff for smaller size Scaffolds(~1.5kb
which is very small). I have attached a Scaffold of 1.5kb with no
predictions and another Scaffold of 28kb. It is of course expected that we
would not get any gene-prediction for small size Scaffolds.

For next maker run would you recommend bootstrap to reduce false positives?

Thanks and regards,
Parul Kudtarkar
