[maker-devel] why no prediction

[Carson Holt]

The structure of the evidence appears to suggest a spurious prediction randomly overlapped by a spurious EST alignment. You would need at least protein evidence overlap to make it believable.  There is heavy discordance among the gene predictors. Also the fact that the gene would be 90% plus UTR if the EST does in fact represent true expression is a big factor.  More likely it’s a pseudogene or semi repetitive region. Not making this a gene was the right call.

I could find the gene model in the "XXXX.all.maker.non_overlapping_ab_initio.transcripts.fasta" file. It is wired because it did have evidence supported.
