Hi Guangming, The parameter is processed in rtkGgoFunctions <https://github.com/SimonRit/RTK/blob/master/code/rtkGgoFunctions.h>.h. It's passed to an itk::ChangeInformationFilter <http://www.itk.org/Doxygen/html/classitk_1_1ChangeInformationImageFilter.html> at the beginning of the rtk::ProjectionsReader.h <http://www.openrtk.org/Doxygen/classrtk_1_1ProjectionsReader.html>. But in the end, there is nothing to explain, it's simply changes the spacing of the input projections. I hope this helps, Simon
