Hi Matthieu, I never used PET data, but once you manage to resample you pet data onto the surface, you will have a file similar to the thickness file for each subjects. Instead of thickness it holds you PET information. From that point on everything should be identical to the thickness analysis

Hi Emily, I've never tried to use unpacksdcmdir but you may try the Osirix tool, it allows you to read in a dicom folder and save a new folder with subfolders according to the sequences that were run. At the same time you can also anonymize your data. Does this help? Best wishes, Barbara

Hi Emily, Yes, Osirix Lite should be sufficient, I think it works by picking File-import and then File-export-export DICOMs (decompression is sometimes helpful). It should be straightforward, just have a go at it. Hope it helps. Best wishes, Barbara On 19/09/2016 00:36, Emily Louise Bell
