+#### Quick QA: export one harmonized image to inspect

+After writing `thickness_covfam` into `/scalars`, you can export one row
+back to an image and open it in your usual viewer as a spot-check. Use
+`--column-index` to select which row from
+`scalars/thickness_covfam/values` to export.
+
+``` bash
+modelarrayio h5-export-nifti-file \
+  --input-hdf5 thickness_harmonized.h5 \
+  --scalar-name thickness_covfam \

+If your workflow uses CIFTI or MIF instead of NIfTI, use the matching
+export command: `h5-export-cifti-file` or `h5-export-mif-file`.
