MS2 fragment spectra missing when they should be there

Hi again,

I'm currently using Shinyscreen to generate plots for the AWEL paper.

I'm missing MS2 fragment spectra which I know are supposed to be there as I've been able to extract and plot them before (using the oooold version of prescreening I used back in Sept-Oct 2019).

Screenshot_2020-06-08_at_17.10.38 Screenshot_2020-06-08_at_17.12.26 -> evidence that MS2 exists; I plotted this using the MS2 peak list extracted as a 'kids.csv' by old prescreening code.

Have double checked that I am using the correct m/z and mzML as inputs and spectra extraction parameters.

What's odd is that Shinyscreen is not detecting the rt; perhaps this is related to my issue? --> Screenshot_2020-06-08_at_17.13.38
