Externalize pgfplotstable with csv file

This is a direct follow-up question to this: Adding units to pgfplotstable header

After fixing the output I tried outsourcing the table. After figuring out that standalone does not work with longtable (thanks to @Jake) I removed that, but even then every time i try to compile with pdfLaTeX I get this error:

! Package pgfplots Error: Could not read table file 't3.dat'. In case you inten ded to provide inline data: maybe TeX screwed up your end-of-lines? Try row se p=crcr' and terminate your lines with \\ (refer to the pgfplotstable manual for details).

where t3.csv is the file where all the data is stored.

My file currently looks like this:

\documentclass{standalone}
\usepackage{pgfplotstable}
\usepackage{booktabs}
\usepackage[allowlitunits]{siunitx}

\begin{document}
\pgfplotsinvokeforeach{100,90,...,10}{
\pgfmathsetmacro\concentration{#1/100*0.25}
\pgfplotstableset{
columns/#1/.estyle={
fixed,fixed zerofill,precision=3,
column type=p{4.5em},
column name={\SI[round-mode=places,round-precision=3]{\concentration}{\mol\per\liter} (\SI{#1}{\percent})}}
}
}
\pgfplotstabletypeset[col sep=semicolon,
columns/Zeit/.style={fixed,fixed ,column type=r},
before row=\toprule,
},
every last row/.style={
after row=\bottomrule
}
]{t3.dat}

\end{document}


So to summarize the whole thing, I tried 2 ways to include this table:

1. Using the standalone class and including the file with \includestandalone{subdir/filename}
2. Using a file without any preamble and \documentclass and using the \input{subdir/filename} method.

Still I'm not able to determine what causes this error. Running Windows 7 and TeXStudio

EDIT

it looks like I am not able to write a file into any directory. so the question should be, why am I not able to write a file?

• Hm, it compiles fine for me using the first method (I didn't try the second). Is the t3.dat file in the subdir folder?

• Did you try running TeXStudio as administrator? Jun 6, 2013 at 20:20

Ok I fixed it but it wasn't as spectacular as I thought

\documentclass{standalone}
\usepackage{pgfplotstable}
\usepackage{booktabs}
\usepackage[allowlitunits]{siunitx}
\begin{document}
\sisetup{per-mode=symbol}
\pgfplotsinvokeforeach{100,90,...,10}{
\pgfmathsetmacro\concentration{#1/100*0.25}
\pgfplotstableset{
columns/#1/.estyle={
fixed,fixed zerofill,precision=3,
column type=p{4.5em},
column name={\SI[round-mode=places,round-precision=3]{\concentration}{\mol\per\liter} (\SI{#1}{\percent})}}
}
}
\pgfplotstabletypeset[col sep=semicolon,
columns/Zeit/.style={fixed,fixed ,column type=r},
before row=\toprule,
after row=\midrule
},
every last row/.style={
after row=\bottomrule
}
]{t3.dat}

\end{document}


looks pretty much the same but since standalone does not work with longtable I removed this part:

\pgfplotstableset{
begin table=\begin{longtable},
end table=\end{longtable},
}


what I forgot was to remove the \endhead command within after row (see first Question)

And I moved all files to the same directory, not sure if this is that important. It is not that pretty but works for me.
