Q.
I entered a scan (or whole set of scans) into my schedule file, but it isn't there now! What's happened
A.
In all likelihood you've failed to either add the scans to your schedule or actually write then to file.
This something that people often don't understand!
Creating a schedule file is a two step process.
First you need to add the parameters for each scan into memory,
then when you are satisified with the whole sequence you write them to disk.
