+\subsection{The {\tt S2M:} module}\label{sect:S2MData}
+
+This module is used to extract macrocoscopic cross-section data from a Matlab-formatted {\sc ascii} file
+generated by the SERPENT Monte Carlo code (see Ref.~\citen{serpent}) and to convert it to the {\sc macrolib} format.
+
+\vskip 0.02cm
+
+The calling specifications are:
+
+\begin{DataStructure}{Structure \dstr{S2M:}}
+\dusa{MACRO}~\moc{:=}~\moc{S2M:}~\dusa{matlab.m}~\moc{::}~\dstr{S2M\_data} \\
+\end{DataStructure}
+
+\noindent where
+\begin{ListeDeDescription}{mmmmmmm}
+
+\item[\dusa{MACRO}] {\tt character*12} name of the required {\sc macrolib} (type {\tt L\_MACROLIB}) object that is created by {\tt S2M:}.
+
+\item[\dusa{matlab.m}] {\tt character*12} name of a {\sc ascii} file, open in read-only mode, containing Matlab-formatted SERPENT information.
+
+\item[\dusa{S2M\_data}] input data structure containing specific data (see \Sect{descS2M}).
+
+\end{ListeDeDescription}
+
+\subsubsection{Data input for module {\tt S2M:}}\label{sect:descS2M}
+
+\vskip -0.5cm
+
+\begin{DataStructure}{Structure \dstr{S2M\_data}}
+$[$~\moc{EDIT} \dusa{iprint}~$]$ \\
+$[$~\moc{IDX} \dusa{idx}~$]$ \\
+$[$~\moc{B1} $]$ \\
+\moc{;}
+\end{DataStructure}
+
+\noindent where
+\begin{ListeDeDescription}{mmmmmmmm}
+
+\item[\moc{EDIT}] keyword used to set \dusa{iprint}.
+
+\item[\dusa{iprint}] index used to control the printing in module {\tt S2M:}. =0 for no print; =1 for minimum printing (default value).
+
+\item[\moc{IDX}] keyword used to specify the occurence index of a flux calculation in the SERPENT output file. This index generally refers to the burnup step.
+
+\item[\dusa{idx}] occurence index.
+
+\item[\moc{B1}] keyword used to specify that diffusion coefficients and other fundamental-mode information are to be recovered from the SERPENT output file.
+
+\end{ListeDeDescription}
