Hi Hamed,
 what I meant is that you should use the full path to every file you read or write:

vmtkimagereader -f dicom -d C:/Users/Hamed/Downloads/Compressed/br1 --pipe vmtkimagevoiselector -ofile C:/Users/Hamed/image_volume_voi.vti

Also, don't start a pipe with --pipe, like
--pipe vmtkmarchingcubes -ifile image_volume_voi.vti -l 300.0 -ofile mc_surface.vtp --pipe vmtksurfaceviewer

Omit the first --pipe, like :
vmtkmarchingcubes -ifile C:/Users/Hamed/image_volume_voi.vti -l 300.0 -ofile C:/Users/Hamed/mc_surface.vtp --pipe vmtksurfaceviewer

(note that I included the full paths to the files).

Hope this helps

Luca
