Two separate documents containing a table of contents figure and caption. Please select a structure or figure representative of your article to appear in the Table of Contents (should your paper be accepted) along with the article title, author names, and page numbers. You may either choose a figure already present in your manuscript, or supply a separate figure and a short legend. Please note that the figure will have to be reduced significantly to fit in the Table of Contents; final size will be 2 x 2 inches or smaller. The figure should be readable at this reduction. If you are selecting a structure or figure already present in the manuscript, you will need to upload it a second time as "Table of Contents Figure."
还有这个Graphical Abstract和Graphical Abstract Legend (TOC Figure)有什么区别呀
