WebFeb 9, 2006 · The second group of gene-finding methods, extrinsic methods, comprises all programs which use data other than the query genomic sequence. Some extrinsic methods use genomic sequences from other species. A cross-species comparison of genomic sequences can help in predicting genes in the given query sequence. A GHMM for gene prediction is a probabilistic model of a random DNA sequence and its random gene structure. It assigns to each pair of a DNA-sequence s and a gene structure φ the joint probability P(φ, s). Based on this model, GHMM-based gene prediction programs find for a given input DNA sequence s … See more In this subsection, we explain how extrinsic information is integrated in the GHMM of AUGUSTUS. We call an individual piece of extrinsic information about the input DNA … See more In order to describe the model AUGUSTUS+ we need to specify the probability distribution (1). The probabilities of gene structures φ and DNA-sequences s is the same as in AUGUSTUS [19]; the … See more AUGUSTUS+. We extend the GHMM used in AUGUSTUS to a GHMM that considers the above types of hints for gene prediction. Let h be the collection of all hints, which have been obtained for the input DNA sequence … See more Suppose we have some (possibly empty) collection h of hints for an input DNA sequence s. We want to examine the effect that an additional hint not present in h has on the predicted gene structure. Clearly, gene … See more
