<div id="RTEContent">Hi all,<br> i've writed a code similar to the one in section 7.12.3 of the guide to read a serie of 131 Dicom file from a directory (each file contain a slice), then i save it into a volume file named "volume.vtk" (i've tried "volume.dcm" too). the reading and saving process was ok since i get well the file volume.vtk, but when i tried to visualize it with VolView for example i get error:<br> ERROR : In C:\kitware\VolView\VolView20\VTK\Graphics\vtkPlaneSource.cxx<br> vtkPlaneSource (0x05D490A0): Bad Plane coordinate system.<br> <br> and the program crash.<br> when i tried to open it with other example i find in InsightApplications i get only the first slice and not a volume...<br> this is my code :<br> <br> <br> <br> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="Generator" content="Kate, the KDE Advanced Text Editor"> <pre> <span style="color: rgb(128, 0, 0);">char</span>* chooserName = fl_dir_chooser(<span
