Gene finding: putting the parts together
... Any isolated signal of a gene is hard to predict. Current methods for promoter prediction, for instance, will have either a very low specificity or a very bad sensitivity, such that they will either predict a huge number of false positives (fake promoters) or a very small number of true promoters. T ...
