Each database homogenize its datasets, giving rise to heterogeneity across databases. Such heterogeneity mainly encompasses different names for a gene and different network representations, generating duplicated interactions that could bias network analyses.

The high-quality networks in Abasy Atlas enable cross-organisms analyses, such as benchmarking studies where gold standards are required.
