When I try exporting a DICOM series after hardening a transform, I find that my DICOMs still look like they were before the transform when they are loaded into Horos, but not ITK-Snap. I did not have this problem when I tried doing this the other day.

Are there any suggestions for how to fix this issue?

The only vague difference I recall is probably when I did the DICOM export. I don’t remember when I was doing this successfully that a default Scalar Volume subfolder would be created.

I’ve outline my steps below:

1. Here is the uploaded MEMPRAGE in the Transform module, prior to any transformations are applied.

2. I’ve adjusted the slider for the transform, but have not hardened it yet.

3. I select the the file name and then click the hardened transform icon.

4. I right click the image sequence’s name in Data and then select “Export to DICOM” and export as the screen shows.
