The Method Editor application enforces these data-dependent scan rules to prevent illogical instrument methods:

The first data-dependent scan must be a data-dependent selected ion monitoring (ddSIM) scan or a data-dependent MS/MS (ddMS²) (level n = 2) scan.
No ddSIM or ddMS² scan can follow a tMSⁿ (level n > 2)
Only a ddSIM or a ddMS² scan can follow a ddSIM scan.
Only a ddMSⁿ or a ddMS⁽ⁿ⁺¹⁾ scan can follow a ddMSⁿscan.
You can have Top N data-dependence for a ddMSⁿ scan by using the Number of Scans setting. You can specify the amount of time or the number of scans to take in a data-dependent node.
