Description

This track shows ab initio predictions from the program AUGUSTUS (version 3.1). for the 02 Jul 2018 Homo sapiens/GCA_002209525.2_HG01352_prelim_2.1 genome assembly.

The predictions are based on the genome sequence alone.

Gene count: 22,110; Bases covered: 1,403,698,078

Methods

Statistical signal models were built for splice sites, branch-point patterns, translation start sites, and the poly-A signal. Furthermore, models were built for the sequence content of protein-coding and non-coding regions as well as for the length distributions of different exon and intron types. Detailed descriptions of most of these different models can be found in Mario Stanke's dissertation. This track shows the most likely gene structure according to a Semi-Markov Conditional Random Field model. Alternative splicing transcripts were obtained with a sampling algorithm (--alternatives-from-sampling=true --sample=100 --minexonintronprob=0.2 --minmeanexonintronprob=0.5 --maxtracks=3 --temperature=2).

The different models used by Augustus were trained on a number of different species-specific gene sets, which included 1000-2000 training gene structures. The --species option allows one to choose the species used for training the models. Different training species were used for the --species option when generating these predictions for different groups of assemblies.

Assembly Group Training Species
Fish zebrafish
Birds chicken
Human and all other vertebrates human
Nematodes caenorhabditis
Drosophila fly
A. mellifera honeybee1
A. gambiae culex
S. cerevisiae saccharomyces

This table describes which training species was used for a particular group of assemblies. When available, the closest related training species was used.

Thanks to the Stanke lab for providing the AUGUSTUS program. The training for the chicken version was done by Stefanie König and the training for the human and zebrafish versions was done by Mario Stanke.
