If it is a small mistake, you can write directly to the editor to explain it. If it is a big mistake, you may have to make a statement and write another article to correct it. If it is a defect, the follow-up research should be to solve the original defect. After studying some papers carefully, I basically found mistakes, some of which are understandable. As long as it does not affect the elaboration of key issues in the article, contact the editor if necessary.

The best way is to take the initiative to tell the tutor, and the tutor will contact the editor, modify the data and resubmit it. Of course, if such problems are found after the paper is hired, you can also contact the editorial department, submit new data, revise it again, or send a revision explanation. Of course, you can also choose to withdraw the manuscript.
