1. Always upload the main LaTeX file first.

2. Upload all supporting files. ALL style sheets, reference files, bibliography files, etc, that are referred to in the main .TEX file and select "Tex/Latex Suppl File". 

3. If any changes are made to the main LaTeX document after all of the supporting files have been uploaded, all files will have to be removed and re-uploaded.

4. We recommend that all image files be one of the following file types:

* ScholarOne Manuscripts supports LaTeX v7.4.5 and earlier.
