As part of a project we will be converting large number of 3D high-resolution scans of biological specimens into volumetric format. Currently most of them are in DICOM or some sort of a image sequence, and we want to use something like NRRD to facilitate easier data exchange and increase usability of these data with 3D Slicer.
However, we also need to make sure we can trace the provenance of the dataset (museum specimen/accession number is the absolute minimum, and possibly few other tags, for example species designation or sex). I am hoping to have a better and more robust method than simply naming the volume with this number and keeping the metadata external. One idea was to use NRRD with a detached text header and keep some of this information as comments. But I am not sure what would happen to them if the user accidentally checkmarks the save option. Would this be retained? Are there other formats more suitable for our use case?
I appreciate any feedback.
