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 which cannot be included in the article because it is too large or the current format does not permit it (such as movies, raw data traces, power point presentations, etc.) can be uploaded during the submission procedure and will be displayed along with the published article.
If a published article has Supplementary Material, where can you find it?
Here are the steps to perform:
Search for the published article page. On the article page (abstract or full text), look at the top right hand side of the page next to the article title, click on the Download article icon to access the supplementary files.
Additionally, in the "TABLE OF CONTENTS" on the left- side column and the button page, if you click on the "Supplementary Material" link, you will be redirected to the respective section
