I have submitted a paper to PLoS Computational Biology and it has been accepted. The paper has three supporting text pieces, which PLOSCB requires to be separate files. So, I split my paper into four files, let's call them
S3.tex. There are cross-references from
paper.tex to each of the
S*.tex documents. I used the
xr package for these. This works fine, but requires that
S*.aux files be present during the compilation of
paper.tex. So, I uploaded
paper.tex and the
S*.aux files to the journal. I just got an email from them saying:
Please ensure that you have provided a single, cohesive .tex file for your LaTex submission. Please send us one complete tex file without the aux files.
How can I do that? Is there any way to sort of paste the
S*.aux files into
paper.tex so that it compiles and correctly resolves cross-references?
