Hi @ldlamini! If you’re asking to use a volume from an earlier (i.e., not the final) iteration of ab initio reconstruction, you can use the low-level interface to select an earlier iteration. When you view the outputs tab of any refinement job, you can open a drop-down menu to see all versions of that volume. You can then use the low-level interface to replace the map input with the desired version.
Do you mind if I ask, though, why you prefer to use one of these earlier results rather than the final result?
