Abstract
Correction for ‘ATR-FTIR spectroscopy with chemometric algorithms of multivariate classification in the discrimination between healthy vs. dengue vs. chikungunya vs. zika clinical samples’ by Marfran C. D. Santos et al., Anal. Methods, 2018, 10, 1280–1285.
The authors regret that incorrect images were included in Fig. 1–3 of the original article. The correct versions of Fig. 1–3 are presented below.

| Fig. 1 Average of the spectra of the three classes cut between 1800 and 900 cm−1, before and after the pre-processing (baseline – automatic Whittaker filter, and Savitzky–Golay smoothing – 15 point window). | ||
