What would be the best approach to predict introns or gene model from RNA-seq/est and genome seq without GT-AG splice site rules?

Would you mind elaborating further on that rationale? U2 and U12 confer to a small class of dinucleotide pairs at the splice sites and are extremely well conserved from plants to animals. While there has been a very small number of non-consensus splice sites reported in the literature, many would agree that these variants are likely due to errors in annotations/interpretations, polymorphic difference between cDNA/genomic, or maybe pseudogene variants.

There is a chance that some of the annotated non-consensus splice sites are due to error in annotation. However, there are several studies which suggests that non-canonical splice-sites really exist. I am working on the species where is possiblity that they have predominantly non-consensus splice site.

Some References,

You could align your reads with STAR this directly gives you information about gaps in the alignment of your reads and therefor introns.
