Single-molecule localization microscopy (SMLM) captures nanoscale detail with fluorescence imaging. As large-area cameras and multiplex imaging become standard, chromatic errors are growing more complex, challenging precise analysis. To address this challenge, we present BeadBuddy, an open-source, user-friendly software that uses images of fluorescent beads to model and correct 3D, spatially varying chromatic errors. BeadBuddy achieves sub-voxel resolution in DNA Fluorescence In Situ Hybridization (FISH) and is applicable across SMLM modalities.
