I’m using the els-cas-templates LaTeX package (doc). I will be submitting to an Elsevier journal, which allows this official package for submission. I have not touched any of the template files. I am editing/building on Overleaf.

I have not provided any ORCIDs for the authors, however there is still a blank ORCID footnote being displayed. How do I suppress that without modifying the template? I have emailed the package authors, but have yet to receive a reply.

Here is my LaTeX author code:

\author[1]{John Smith}
\ead{[email protected]}
\author[2]{John Doe}

The title page footnotes look like this:
enter image description here

But they should look like this (format)(copied from published article):
enter image description here

Also there is an email img instead of the word "E-mail address". I can ask that as a separate question if requested.

    Notice, however, that some journals require ORCIDs, some even for all authors. I mean, there might be a reason for the template to do what it does. Dec 11, 2019 at 8:41

Simply put,

\renewcommand{\printorcid}{}  % this will make this function do nothing.
\ ... 

This does involve making a small edit in the template. As a work-around it worked when I commented out the line with \printorcid in the .sty file.

  • I've been waiting for other suggestions, hoping that I could overwrite the behavior with a redefinition in the main file without touching the template/preamble. If I don't get any, I will accept this answer. Thank you.
