-## Conceptual design
-
-1. Generate a ["primary" scans](#terminology) to [other scans](#terminology) mapping file.
-2. Deface primary scans
-   with [@afni_refacer_run](https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/tutorials/refacer/refacer_run.html) program
-   developed by the AFNI Team.
-3. To deface remaining scans in the session, register them to the primary scan (using FSL `flirt` command) and then use
-   the primary scan's defacemask to generate a defaced image (using `fslmaths` command).
-4. Visually inspect defaced scans with [VisualQC](https://raamana.github.io/visualqc) deface tool or any other preferred
-   tool.
-5. Correct/fix defaced scans that failed visual inspection. See [here](FILLINTHEBLANK) for more info on types of failures.
