Hi Kate,
It might be possible that there is a modal popup (one that freezes the
rest of Analysis while waiting for a user response) present somewhere in
the background, but which is obscured by various windows in the
foreground. We use such popups to display warnings that indicate when we
have an unfittable graph for a peak group, and things won't continue until
you click [OK]. This is consistent with some series halting at the start
and some part way through, as it is arbitrary where in the list an
unfittable group may be found.
Please have a look to see if there is a warning dialog box by minimising
all but the main Analysis window.
I will look into the code to make sure that any warnings are displayed in
front of all the other Analysis windows. - But the issue may be related to
your particular windowing system - e.g. if the focus follows the mouse and
causes whichever window is beneath to come to the top, thus obscuring any
message.
If you cannot find any dialog box, it may be best to send me your project
so that I can have a detailed look.

Yes, that's the whole idea. One reference spectrum is all that is needed.

Sounds like a bug relating to None vs 0.0 in the Python. I will have a
look into this next week. In the mean time try using a very small non-zero
value as a substitute.

No. Only the values are important.
