I appear to be having a problem with embedding images in a tabular enviroment. I getting the following error:
! LaTeX Error: File `\unskip ' not found.
and here is the offending piece of code. The compiler points me to the line beginning with \multicolumn
\begin{figure}[H]
\centering
\begin{tabular}{@{}cc@{}}
\includegraphics[scale=0.22]{lig_nontp_align.png} &
\includegraphics[scale=0.22]{transporthist.png} \\
\multicolumn{2}{c}{\includegraphics[width=.23\textwidth]}
\end{tabular}
\caption{\textit{Left:} Non-transport and ligand proteins aligned to the ligand HMM model. \textit{Right:} the three different sub-types of transmembrane proteins aligned to the ligand HMM model. }
\end{figure}
I can find problems to do with "\unskip" form googling, but not quite in this capacity. what seems to be the problem?
Thanks.

with no file name: is the really in your file? If so, it's a likely culprit as the command will grab whatever follows. – Joseph Wright♦ Dec 18 '13 at 11:46
