Hello all,
My dcm data has ROIs stored at 0x6000.
After converting to Nifti using dcm2nii, I couldn't fine the ROI information any more.
Does dcm2nii store ROI data somewhere after converted to Nifti from dcm? If yes, how can I find it?

Thank you very much for your help.

I have added experimental support for converting up to 16 overlays from each DICOM as described by the Overlay Plane Module. This is included in v1.0.20200904 of the development branch.

For Linux, you can compile the developmental version of dcm2niix with these commands:

git clone --branch development https://github.com/rordenlab/dcm2niix.gi...
cd dcm2niix/console
make
./dcm2niix


Windows users should be able to get a compiled version from AppVeyor (click the "Artifacts" button). Please test. this extensively. It does not support the retired "burned-in" overlays, rather the modern binary bitmaps. I have very few examples, and it is unclear how (or if) these features are supported in enhanced DICOM.
