Erratum: Integrative analysis and machine learning based characterization of single circulating tumor cells (J. Clin. Med., (2020) 9, 1206, 10.3390/jcm9041206)

In the published manuscript [1], the bibliographic items were incorrectly rendered. The following three references are missed [2–4]. Due to this, the order and the citations corresponding to several references were misplaced. We added them between Szczerba, B.M., et al. (2019) and Zhang, X. (2018) and numbered them as [29–31] in the original manuscript [1]. The citation has now been inserted in Section 2. Materials and Methods, 2.2. Data Pre-Processing, Paragraph 1. The subsequent citations in the main text have also been updated. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
