Frontiers journals do not support pushing important results and information into supplementary sections. However, data that are not of primary importance to the text, or that cannot be included in the article because they are too large or the current format does not permit it (such as movies, raw data traces, PowerPoint presentations, etc.) can be uploaded during the submission process. Any supplementary material files will be included in the review forum and the reviewers will have access to them during the review.

When you upload a supplementary material file, the submission form will attribute it a category and number depending on its file type. If the category does not correspond to what is needed, it is possible to edit it. As for figures, the numbering can be changed by dragging and dropping.
The possible file types and categories are as follows:

Please ensure the numbering and naming of all supplementary files is consistent – for example, please do not upload a file as Supplementary Table 2, when you have named and saved it as ‘Supplementary Table 4’.

You should upload files containing more than one table/figure as a Data Sheet or Presentation. The Image and Table naming categories are reserved for files containing only one figure and table, respectively. Files containing supplementary text, protocols and/or references should also be uploaded as a Data Sheet or Presentation.
