LyX ⇒ Including a Diagram from an external File

[NewLyxUser]

When I converted a tex file to lyx, I got lots of errors on this particular part, which I was unable to resolve. Any ideas?
In the original tex file it was as follows:

Code: Select all

\begin{align}
\dot{x}& =Ax+bu,  \notag \\
y& =c' x,
\end{align}%
and a function~$\phi \in S_{k}$.
\begin{figure}[tbp]
\begin{center}
\input{abst.pstex_t}
\end{center}
\caption{}
\label{fig:abs}
\end{figure}

The contents of abst.pstex_t are:

Code: Select all

Hi,

I don't get an error if I put those parts into separate documents, complete that and compile. So the error is probably somewhere else in your code. It would be good if you would tell us the error messages you got, besides mentioning there are some.
