GeneMark-ES Gene Finding

The GeneMark-ES Gene Finding plugin offers an innovative approach to finding genes in eukaryotic genomes along with solving the parameter estimation problem by iterative self-training.

GENE PROBE Inc., the developers of the core components of GeneMark-ES, have developed an original implementation of the Viterbi algorithm for hidden semi-Markov Model of the eukaryotic genomic sequence. Gene Probe, Inc. has created and refined algorithms for gene prediction in genomic sequences for more than twenty-five years. GeneMark-ES gene finding plugin was further optimized for gene finding in fungal genomes.

GeneMark-ES is an ab initio gene finder designed to predict protein coding genes possibly interrupted with introns, a typical feature of gene organization in  eukaryotic genomes. The algorithm parameters are genome-specific and are determined by unsupervised training on a given (novel) genomic sequence. The GeneMark.hmm algorithm uses a hidden semi-Markov model describing the functional and structural organization of a eukaryotic sequence.

Accurate gene finding in eukaryotes made easy

• The GeneMark-ES gene finding plugin provides full automation. All parameters necessary for analysis are automatically trained.
• The GeneMark-ES plugin can be readily connected with the Extract Annotations tool and the BLAST tools of QIAGEN CLC Genomics Workbench or QIAGEN CLC Genomics Server.
