Hi,

I am trying to apply the iterative Yang for PVC. I prepared the input files according to the instructions, but somethign seems to be wrong with the PET header file. The PET is coregistered to the MRI space and I also tried fslcpgeom between the two, however, I seem to get the following error:

petpvc -i /Users/nj/build13/test/sub.mc.mrcoreg.nii -m /Users/nj/build13/test/sub_mask.nii -o /Users/nj/build13/test/sub.PVC.nii --pvc IY -x 6.0 -y 6.0 -z 6.0 [--debug] Too many arguments specified in your command line! Skipping extra argument: [--debug] WARNING: In /Users/nj/ITK01/Modules/IO/MRC/src/itkMRCHeaderObject.cxx, line 140 MRCHeaderObject (0x7fcf1c007400): Some header data does not have sensable values

[Error] Cannot read PET input file: /Users/nj/build13/test/sub.mc.mrcoreg.nii

itk::ExceptionObject (0x7fcf1af09dd8) Location: "unknown" File: /Users/nj/ITK01/Modules/IO/MRC/src/itkMRCImageIO.cxx Line: 250 Description: itk::ERROR: MRCImageIO(0x7fcf1af08230): Unrecognized header

I am not sure what the header needs contain for it to be recognized. Any help will be appreciated. Thanks!

Try renaming /Users/nj/build13/test/sub.mc.mrcoreg.nii to something like Users/nj/build13/test/sub_mc_mrcoreg.nii. Also, --debug does not need the braces around it. This was to signify that --debug is a optional flag.

Replacing the '.' with '-' worked! Thank you so much.
