Hi,
I do not believe there is such a tool in AFNI. The DICOM images come in varied formats and data types, and come after their own headers. While I have done a similar operation before, it was by:
- converting them to datasets
- applying the operation
- writing the raw data back into the DICOM file (after the header)
Since most software handles NIFTI images, would it be possible to do such work using that format instead?
