The paper introduces S2IsoMEr and METASPACE tools to handle molecular ambiguity in spatial and single-cell metabolomics through bootstrapping for enrichment analysis.

The paper evaluates spatial metabolomics protocols and technologies, showing extensive metabolite coverage and comparable results across imaging MS methods.

The paper evaluates pixel-cell deconvolution methods in spatial single-cell metabolomics using fluorescein as ground truth, showing that weighted average outperforms linear inverse modeling and demonstrating the impact of ion suppression.
