[Tex/LaTex] Search path for pgfplotstable

Question

I'm creating some tables reading values from .dat files. All these files are placed in a subfolder. Is there a way to tell \pgfplotstabletypeset the search path to that subfolder? Something similar to \graphicspath?

Extra info: I have my files organized in subfolders but I'm trying to submit a paper to a journal and I cannot create subfolders on their build servers (I have to upload the files one by one and they end up in a single folder). I also cannot set TEXINPUTS (unless there's a way to do it from the main .tex file).

PS: I find it frustrating that scientific journals have retarded tex build servers.

Answer 1

There is no such builtin feature in pgfplotstable. In fact, this question resembles an old feature request.

While thinking about alternatives, I got the following idea:

You could place some dummy text file like thisisremuspc.file in your aside of your local directory structure and add something like

\IfFileExists{thisisremuspc.file}{\def\todirectory##1{##1}}{\def\todirectory##1{}}

to your preamble. Whenever you load a data file, you could write

\addplot table {\todirectory{my/local/sub/dir/}file.dat};

I have had no time to test this approach, but it should work (up to, maybe, magic due to the # characters). The idea is that todirectory would expand to an empty string if you magic file is missing. Would that do the job (assuming it works)?
