Dear Salvatore,
Thank-you for making your DICOM data available. This type of data is much easier to work with compared with the jpeg files you provided originally. I have open-source packages (oro.dicomand oro.nifti) that run in the R programming language (www.r-project.org) specifically to read in DICOM data and convert it to another typical format = NIfTI. I will work on your data and convert it from DICOM to NIfTI in the near future.
I wish you well and keep strong!
cheers…
Brandon
