This section of my webpage will be occasionally updated with some helpful posts that can help people sort out some of the problems that I faced. Feel free to share the posts with others if needed.
How to submit your article to a journal/arXiv:
Open the overleaf and check for everything one last time. Compile it. You should be satisfied with yourself for the submission.
Go to submit in the upper section and select arXiv. This will give multiple options — but select the ‘download file with .zip extension.’
After a while, it will download a .zip file containing all the necessary files, e.g., .tex files, a .bbl file, a .bib file, and a file containing all the plots (remember that the plots should be in .pdf format to get compiled in arXiv and any other journal).
After downloading the project from overleaf, the plots will be in .eps format, because you have used it. Open the .tex file on your desktop (using texmaker or something like that) and compile the project once. It will create a copy of the .eps files in .pdf format, which can then be renamed for future use (use the same name used in .eps format).
Once the renaming is done, change the .eps extension in the .tex file for each plot with .pdf and recompile it. At this point, the graphics path also should be removed, and all the plots in the project should be kept in the same directory as the .tex file.
Make a directory with a name as you wish and put the main .tex file, associated .text files, .bbl file (reference file), and all plots with .pdf extension and compress everything in a .zip file.
Upload the .zip file to the arXiv/journal server. It should compile the project without any errors.
Go ahead with the submission.
Thank you.
