Hello!

I'm trying to reconstruct PET images in nifti format using the SIRF VM. SIRF is the Synergistic Image Reconstruction Framework that uses the STIR module in image reconstruction. As I understand it, only images with the interfile .hv and .hs formats are usable with this module, and no Nifti or Dicom files are readable. Am I correct? I also changed the nifti format to h33, i33, and v formats using the XMedcon application in an attempt to load converted interfile formats to my code.
However, the code I use

image_data = pet.ImageData('path/to/file/m000-31013_AV451_S_E.v')

renders this error:

ERROR: Error opening file /media/sf_DATABASE/m000-m000-31013_AV451_S_E.v

and that

the reconstruction engine output may provide more information

I get the same error message when using h33/i33 as well.

If you could help me load up nifti or dicom files with this module, I would much appreciate it. Thanks!
