Checklist for new results

[constantinpape]

Things to check for in the new results:

• Does the infected cell detection work properly now? (Cell outlier detection has been deactivated).
• Compare sum and mean based scores. (Sum / mean are computed correctly = with / without nuclei now)
• How does the new barrel correction look now.
• Check the plate plate5rep3_20200507_113530_429; something was weird with that one, feature computation took 3 times longer than for the other plates.
• For future runs: can we estimate better parameters for the QC

• For the sum scores in several plates the sums for the control cells are on average higher than for the infected. We need to figure out why that is (IgG_diff_sums = IgG_infected_q0.5_sums - IgG_control_q0.5_sums) => Control cells are larger than infected cells #72

new barrel correction looks now much better!
👏 @imagirom

1. did you compute for each plate it's own correction or did you average over all plates?
2. could maybe still be a bit better, upper left and lower left are a bit darker, around 50-100 gray values (I think in all channels). Here I blurred an image in an H01 well to make it visible:

@tischi Nice!

• did you compute for each plate it's own correction or did you average over all plates?

I averaged over all the plates, to reduce the local variations. We could do it for every plate individually, but that would not work well if some new plate has only few wells filled.

• could maybe still be a bit better, upper left and lower left are a bit darker, around 50-100 gray values (I think in all channels). Here I blurred an image in an H01 well to make it visible:

If that is the case for all plates, it is a bug, since with the current method the average over all images should be a totally flat image.
It might also have to do with there being less cells on that side of the plate on average.

@tischi thanks for checking all things.
What's left to do is estimating better QC parameter ...
I will export fixed cell tables for this soon.
