Short answer is, yes, as of ~4 minutes ago… We’ve just added options to
mrconvert to manipulate generic header entries/properties. Once you update, you should be able to anonymise any images (DICOM, NIfTI or whatever) by clearing or setting the
comments field (the only field where MRtrix3 would store patient-confidential information right now). For example:
mrconvert DICOM_folder/ -clear_property comments out.mif
mrconvert in.nii.gz -set_property comments anonymous out.nii
And if you use the MRtrix3 option shortening feature, you can write it more simply like this:
mrconvert DICOM/ -clear comments out.nii
Hope this does the trick!
