The MultiOmics Explainer: Explaining Omics Results in the Context of a Pathway/Genome Database
We describe the MultiOmics Explainer, a new tool within the Pathway Tools software suite that leverages what is known about an organism’s metabolic and regulatory network to suggest explanations for the results of omics experiments.

Metabolic Route Computation in Organism Communities
We developed an efficient software tool to search for metabolic routes that include metabolic reactions from multiple organisms.

Using pathway covering to explore connections among metabolites
Pathway Covering is a new algorithm that takes a list of metabolites (compounds) and determines a minimum-cost set of metabolic pathways in an organism that includes (covers) all the metabolites in the list.

A Comparison of Microbial Genome Web Portals
This article compares the capabilities of the major microbial genome web portals to aid researchers in determining which portal(s) are best suited to their needs.

Evaluation of reaction gap-filling accuracy by randomization
We report on computational experiments of reaction gap filling in which we generated degraded versions of the EcoCyc-20.0-GEM model by randomly removing flux-carrying reactions from a growing model.
-
How accurate is automated gap filling of metabolic models?
Here we compare the results of applying an automated likelihood-based gap filler within the Pathway Tools software with the results of manually gap filling the same metabolic model.
