Gene Finding: Gene models construction, splice sites, protein-coding exons

Total 506 genome-specific parameters are available for genefinders of FGENESH suite

The programs usage in Scientific publications

FGENESH is very fast and accurate ab initio gene prediction program - for more details, see FGENESH help. Its variants that use similarity information: FGENESH+ (similar protein), FGENESH_C (similar cDNA), FEGENESH-2 (two homologous genomic sequences) greatly improve accuracy of gene prediction when such similarity information is available. These programs can be accessed here.

Our best gene finder Eukaryotic genome annotation pipeline Fgenesh++ (see flowchart) cannot be accessed at our site due to computing resources limitations but can be licensed for automatic annotation of genomes with quality similar to that of manual annotation. Fgenesh++ includes the following steps:

  • a) Mapping known mRNAs from RefSeq or full-length transcripts assembled from NGS RNASeq reads by Trinity (MRNA_MAP program);
  • b) Mapping known proteins (from a subset of OrthoDB or NR database) to a genome (PROT_MAP program);
  • c) Identification of splice sites by mapping a set of known ESTs or partial transcripts assembled from NGS RNASeq reads;
  • d) Identification of ab initio gene models.

FGENES, FGENES-M, FGENESH_GC and SPLM can be used on human sequences only.
BESTORF and Fsplice can be used with 296 organisms sequences.
SPL can be used for human, Drosophila, nematode, S.cerevisiae, and dicots.
