Hi Justin,

We (Pratip and I) think it may likely be your data - we have observed 
that the early time points of collection in a flow run tend to have the 
most errors.  Pratip can speak a little more to the technical causes of 
this.  We appreciate your comments and look forward to the results of 
your tests.

This seems odd to me. I attached two figures. The figure called "A..." looks like most other figures, where the first compartment is labelled for removal. And the other figure, called "B...", is my unique case where, I believe anyway, the first compartment should be removed, but not the second. Are all these files somehow accidentally removing the first compartment? Or do you think it is the case that all these files have bad data at the beginning?
