  In a recent article [Vetter and Iber, Nat. Commun. 13, 1145 (2022)], we
demonstrated that single morphogen gradients in the developing mouse neural
tube can carry sufficient positional accuracy to explain the patterning
precision of progenitor domain boundaries. Zagorski et al. had previously
concluded otherwise [Zagorski et al., Science 356, 1379-1383 (2017)], based on
methodological inconsistencies that we have revealed. The authors now comment
on our work with a Matters Arising letter. We rebut their criticism point by
point in the Supplement, and summarize the main aspects here.
