Overview

GECCO is a fast and scalable method for identifying putative novel Biosynthetic Gene Clusters (BGCs) in genomic and metagenomic data using Conditional Random Fields (CRFs).

GECCO is developed in the Zeller group and is part of the suite of computational microbiome analysis tools hosted at EMBL.

Quickstart

Setup

GECCO is implemented in Python, and supports all versions from Python 3.6. Install GECCO with pip:

$ pip install gecco-tool

Or with Conda, using the bioconda channel:

$ conda install -c bioconda gecco

Predictions

GECCO works with DNA sequences, and loads them using Biopython, allowing it to support a large variety of formats, including the common FASTA and GenBank files.

Run a prediction on a FASTA file named sequence.fna and output the predictions to the current directory:

$ gecco -v run --genome sequence.fna

Output

GECCO will create the following files once done (using the same prefix as the input file):

  • {sequence}.features.tsv: The features file, containing the identified proteins and domains in the input sequences.

  • {sequence}.clusters.tsv: If any were found, a clusters file, containing the coordinates of the predicted clusters, along their putative biosynthetic type.

  • {sequence}_cluster_{N}.gbk: If any were found, a GenBank file per cluster, containing the cluster sequence annotated with its member proteins and domains.
