Ce140 ppm?

MButton

My Iolite version 4.5.4 has stopped outputting intermediate or output channels for Ce140. The problem occurred part way through crunching multiple detrital zircon datasets. The first dataset was fine but now I cannot get any data for Ce. The input channel shows data. The only difference between the datasets is that the ones not working have more analyses in them (>200) whereas the first has <100.
I've tried all possible variations in DRS settings I can think of.
Any help with this would be much appreciated.
Cheers

I think you should check the standard Ce information.

For anyone interested, we had a look at Mark's dataset, and the problem in this case was that the auto smoothing spline failed to converge for the Ce140 baseline resulting in a null spline that would affect all subsequent calculations for Ce140. We are planning to make it more obvious to the user when the auto smoothing spline fails, and will suggest changing the spline type.

All the best,
