Since then, a number of other genome annotation systems have been established-ranging widely in scope, functionality and data analysis philosophies. The fully localized annotation pipeline enabled the analysis of confidential or otherwise sensitive sequences without the need for remote data access or otherwise transmitting sequences. In 2003 the prokaryotic genome annotation pipeline GAMOLA (Altermann and Klaenhammer, 2003) was developed with the aim of providing microbiologists with a user friendly system for effective and reliable (draft) genome annotation. One of the primary objectives in the subsequent data analyses is the identification of genes and, where possible, the prediction of their respective biological functions. Recent deep sequencing projects have generated metagenomic datasets that reach sufficient coverage to assemble genes, operons and-in some cases-larger contigs and draft genomes (Ross et al., 2016 Sangwan et al., 2016), granting insights into the non-culturable biosphere.

The advent and continued rise of Next Generation DNA sequencing has enabled microbiologists to investigate more and more microbes on a genome level.

The software is available free of charge for academic use. New functionality can easily be added upon user requests, ensuring that GAMOLA2 provides information relevant to microbiologists. The development of GAMOLA2 is ongoing and community driven.

GAMOLA2 is intended to be run under a Linux environment, whereas the subsequent visualization and manual curation in Artemis is mobile and platform independent. In addition to genome annotations, GAMOLA2 features, among others, supplemental modules that assist in the creation of custom Blast databases, annotation transfers between genome versions, and the preparation of Genbank files for submission via the NCBI Sequin tool. A modified and adapted version of the Artemis Genome Viewer (Sanger Institute) has been developed to leverage the additional features and underlying information provided by the GAMOLA2 analysis, and is part of the software distribution. GAMOLA2 has already been validated in a wide range of bacterial and archaeal genomes, and its modular concept allows easy addition of further functionality in future releases. GAMOLA2 represents a wrapping tool to combine gene model determination, functional Blast, COG, Pfam, and TIGRfam analyses with structural predictions including detection of tRNAs, rRNA genes, non-coding RNAs, signal protein cleavage sites, transmembrane helices, CRISPR repeats and vector sequence contaminations. Here we announce the release of GAMOLA2, a user friendly and comprehensive software package to process, annotate and curate draft and complete bacterial, archaeal, and viral genomes. igORFs may be determined either based on ORF orientation (i.e., only genes on the sense or anti-sense direction are considered when defining the respective intergenic regions, resulting in two separate igORF predictions) or by flattening the gene model (i.e., genes in both orientations will be considered for the determination of intergenic regions).Įxpert curated annotation remains one of the critical steps in achieving a reliable biological relevant annotation. The algorithm can be adjusted by setting a minimum igORF length and by how far a predicted ORF may reach into an existing one. (5C) The Intergenic Blast setup supports default or custom Blast databases for the identification for putative intergenic ORFs (igORFs). Ribosomal binding sites may be predicted using RBSfinder (Suzek et al., 2001). To reduce run-time, intergenic Blast results can be re-used from previous runs, as long as the respective input file remains unchanged. Glimmer 2 or 3 can be chosen alternatively and combined with Prodigal, Critica and an intergenic Blast output. (5B) Supported gene callers currently available to generate an additive gene model. Further customisation enables legacy support, the level of verbosity and the number of domains shown in the annotated Genbank file.
