I am writing a journal article for submission to Review of Scientific Instruments (AIP Publishing). Their officially supported method of writing in LaTeX is using Overleaf. I was going to be away from an internet connection for an extended period of time, so wanted to download the LaTeX document for working offline.

I navigated to this website, opened as a template, then went to the menu and downloaded the source zipped folder. https://www.overleaf.com/latex/templates/template-for-submission-to-aip-publishing-journals/xhsskcchtbxf

Upon opening the aiptemplate.tex file and attempting to compile, I get the following error message:

File 'aps12pt4-1.rtx' not found. ...intsize\expandafter{\@pointsize@default}

  • (I'm on support staff at Overleaf.) Some AIP journals (including RSI) still use RevTeX 4.1, this is why we have both templates available on Overleaf. If you saw an error about aps12pt4-1.rtx not found when compiling locally, you may need to install the revtex4-1 package using your TeX distribution's package manager: ctan.org/pkg/revtex4-1 Commented Apr 7, 2022 at 20:43

Apparently Overleaf (or AIP Publishing) needs to update their template. The package revtex4-1 is no longer contained in some tex packages, so the change was as simple as changing this line:




Overleaf also recognizes revtex4-2, so you're safe to change this on the version in Overleaf as well.

  • Erh, revtex4-1 is no longer in miktex, but according to tan texlive still provides it
