NIfTI images from `t1-linear` are saved as `float64` #622

Open SimonaBottani opened 2 years ago

SimonaBottani commented 2 years ago

Outputs of the pipeline t1-linear are saved as float64, which is heavier than saving them using uint8 (as done by SPM pipeline t1-volume)

Information is available in the header of the DICOM in the field datatype

Which raises the following question: in which precision do we want our NifTi stored in the end? Aka, the file size vs dynamic range dilemma.

ghisvail commented 2 years ago

Back in my PhD days, we were using short integers (int16 / uint16). I don't know the rationales for this choice at the time.

ghisvail commented 2 years ago

As discussed with @nburgos, short integers should be enough for storing MRI and PET modalities with a reasonable dynamic range.
