Run Refinement

TOPAS can run this refinement if multiple scans are loaded in, but there can only be one scan active at a time or the refinement will run the most recent scan and apply that data for all scans.

1. Go to the parameter window and look at all the scans loaded in.
2. Figure 21. One Active Scan and one inactive scan Image Removed Image Removed Figure 20. Two Active ScansThe The colored box next to the scan indicates that a scan is active. Clicking on the box alternates it between 'active' and 'inactive'. In Figure 20 there are two active scans, quartz is blue and Illite is black. In Figure 21 the white box next to Illite illustrates that this scan is now inactive.
