LyX template and layout for PNAS, derived from the PNAS Overleaf template

LyX template and layout for PNAS

This repository provides all necessary files to use the LyX editor, version 2.2 or later, in the preparation of a LaTeX file for submission to the Proceedings of the National Academy of Sciences of the USA (PNAS), following the latest (as of May 2019) template provided by PNAS.

In particular, it provides the following:

• A LyX layout file pnas-new.layout: this was originally derived from the layout file found here, but it was heavily modified and adapted to the new template and classes introduced by PNAS in 2016.
• A template lyx file, pnas-new-template.lyx, and several accompanying files (figures, LaTeX classes, an example bibliography, etc.): this file is directly derived from the original template files, which are available at this link. The original template is distributed under the terms of the LaTeX Project Public License 1.3c. The template was adapted to work under LyX 2.2 or later and it is released under the same license as the original; except for the title and a few LyX notes, no other modifications were performed over the content of the original template. All auxiliary files were left unchanged, except for a small fix in "pnas-new.bst" (a function definition was moved to avoid an error).

NOTE: This is not an official repository, I am not the author nor the maintainer of the original PNAS template.

Installation

After you have downloaded the contents of the repository, you should install the LyX layout file and the LaTeX bst, sty and cls files.

Installing the LaTeX files

First, you need to locate your system directories for LaTeX files. To do this, open LyX and go to Tools->TeX information. Check the Show path option, and look at the directories where the other files are installed. For example, LaTeX classes and styles may be installed in the /usr/share/texlive/texmf-dist/tex/latex/ directory, and BibTeX styles may be installed in the /usr/share/texlive/texmf-dist/bibtex/bst/ directory. I suggest creating a directory called pnas-new under the LaTeX classes/styles system directory, and copying all the *.cls, *.sty and *.ldf files from this repository there; then, you should copy the pnas-new.bst file under the BibTeX directory.

After you copied all files, you should update the LaTeX package information, running the command sudo texhash.

Then, you should update the LyX information: open LyX and choose Tools->reconfigure from the menu.

Installing the LyX layout file

Find out what is your LyX user directory: open LyX and run Help->About LyX from the menu, and read it from the information displayed there. For example, on Linux it should be ~/.lyx.

Copy the pnas-new.layout file under the layouts subdirectory (e.g. ~/.lyx/layouts/ on Linux). Then run Tools->reconfigure from LyX. The new layout should be available upon restarting LyX.

Usage

Just edit the template under LyX. When you are ready, you can simply export the resulting file using File->Export->LaTeX (pdflatex) and it should work with the PNAS submission system.
