The ngKLAST platform

ngKLAST - formerly KoriBlast - sequence search alignment structure tree phylogenetic bioinformatics genomics proteomics Software design bioinformatic analysis biological databanks biological information systems

ngKLAST 4.4 is a software providing convenient tools to analyze, align and compare genetics and genomics sequences, as well as metagenomics and next-generation sequencing data (NGS). ngKLAST includes the KLAST high-performance sequence similarity search tool.

With an easy-to-use workflow engine and a unified set of data viewers, the ngKLAST platform makes sequence databanks exploration accessible to every life science researcher. Sequence similarity search results can be enriched with biological classification data, such as NCBI Taxonomy, Gene Ontology and Enzyme.

Practical use cases of ngKLAST on next-generation sequencing data (NGS)

  ngKLAST can be used for:

> metagenomics, microbial communities analysis. Read more about the applications of ngKLAST for functional metagenomics analysis
> full genome & proteome comparisons
> microarray reannotations
> taxonomy & phylogenetic analyses
> pathways explorations
> functional & structural studies of proteins
> public and personal databanks management

The two Editions: ngKLAST vs. ngKLAST-LE

ngKLAST is available with two releases.

The full edition of ngKLAST contains all the features above mentioned, especially a local KLAST engine as well as the Databank Manager. It is intended to be used on a desktop workstation.

ngKLAST-LE is the Light Edition of the software intended to be used for client-server installation in cooperation with the KLAST Server (see below). In this edition, ngKLAST-LE does not include a local KLAST engine, nor the Databank Manager since KLAST jobs are executed remotely using a KLAST Server.


Boost your work with the KLAST Server

ngKLAST can be used with the KLAST Server (or KServer). This software enables the use of a dedicated computer infrastructure to run KLAST jobs (Klast comparison + data retrieval + data filtering). The server software is compatible with SGE/OGE and PBS-Pro jobs scheduling systems.

Here is a snapshot of the two main solutions available to deploy the KLAST server:
