We know they could be helpfull. We shall add them some day.<br>
Any contribution is welcome.

+ <LI> <TT>gdcm::SerieHelper()</TT> has a new method
+ <TT>void AddGdcmFile(File *header)</TT>, that allows aware user to
+ create a '<TT>FileList</TT>' (actually a
+ <TT>std::vector< File* > </TT>).<br>
+ The <TT>FileList</TT> created this way will be the
+ 'first one' in the <TT>gdcm::FileHelper()</TT> (retrieve it with
+ <TT>FileList *GetFirstCoherentFileList()</TT> ).<br>
+ It may be sorted using <TT>OrderFileList</TT>.<br>
+ No 'coherence check' will be performed on this <TT>FileList</TT>
+ before sorting.<br>
+ It may be passed to a <TT>vtkGdcmReader</TT>

+ <LI> <TT>vtkGdcmReader</TT> can now get the result of

+ s->OrderFileList(l);
+
+ vtkGdcmReader *gr = new vtkGdcmReader();
+ gr->SetCoherentFileList(l);
+ gr->Update();
+ </pre>
+ This works with a directory that contains only one '<TT>Serie</TT>'
+ (same <TT>Serie UID</TT> for all the images).<br>
+ If it contains more than one <TT>Serie</TT>, you'll have to loop
+ on the Series, using <TT>GetNextCoherentFileList()</TT>;<br>
+ It will be up to the user to delete the <TT>gdcm::File</TT>.
