Say I want to find as many protein coding genes as possible. I have valid verification approaches (whether a predicted gene is actually translated in some cell line). Thus I would want a gene prediction tool that can find as many candidates as possible, and high false positive rate is actually more desirable than low false positive rate (or: some confidence criteria can be relaxed to achieve this). Also I would prefer de novo prediction than those that need huge training dataset. Can someone name suitable tools? Thanks!
