Could someone please help me convert this score so it can be played in Dorico?

Steven, this is a double post of Mr. @NIER
we have dealt with it already.

I imported a sheet music, but the last part is cut off. What can I do?

If it is Thalberg piano music, you might be dealing with rather complex tuplets.. I can have a look later (I am writing from my phone at the moment).
