Gene prediction with a hidden Markov model and a new intron submodel

Stanke, Mario, Waack, Stephan·2003·Bioinformatics

Abstract

Motivation: The problem of finding the genes in eukaryotic DNA sequences by computational methods is still not satisfactorily solved. Gene finding programs have achieved relatively high accuracy on short genomic sequences but do not perform well on longer sequences with an unknown number of genes in them. Here existing programs tend to predict many false exons. Results: We have developed a new program, AUGUSTUS, for the ab initio prediction of protein coding genes in eukaryotic genomes. The program is based on a Hidden Markov Model and integrates a number of known methods and submodels. It employs a new way of modeling intron lengths. We use a new donor splice site model, a new model for a short region directly upstream of the donor splice site model that takes the reading frame into account and apply a method that allows better GC-content dependent parameter estimation. AUGUSTUS predicts on longer sequences far more human and drosophila genes accurately than the ab initio gene prediction programs we compared it with, while at the same time being more specific. Availability: A web interface for AUGUSTUS and the executable program are located at http://augustus.gobics.de. Supplementary Information: The datasets used for testing and training are available at http://augustus.gobics.de/datasets/ Contact: mstanke@gwdg.de *To whom correspondence should be addressed.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Augustus is an ab initio gene prediction tool that uses a generalized hidden Markov model (HMM) for gene prediction.

  • Extrinsic evidence such as transcriptome sequences or annotations of closely related genomes can be provided as additional files to Augustus, modifying probabilities during prediction.

    “Extrinsic evidence such as transcriptome sequences or annotations of closely related genomes can be provided as additional files, which modify the probabilities during prediction (Stanke and Waack 2003, Hoff and Stanke 2019).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
