View Profile## Looking for the phenotype in Gr28bd+TrpA1>Chrimson

I have decreased the light intensity to around half of what it previously was. The result do not show any clear phenotype. The ‘logical PI’ looks kind of inverted because I actually have plotted it so that positive means light, negative means no light. A total of 30 flies were tested: some of them with right, other with left reinforcement

## Writting the analysis for the joystick experiments with Gr28bd+TrpA1>Chrimson

Example of a trace within the different trainning/test segments

Inter sampling interval just to check

10 experiment segments with alternating no reinforcement/reinforcement

The same as above but for the 3 platforms that ran in the same batch

Trace dynamics when the light is ON (blue) and OFF (red). Working on nicer visualization in general

## Modelling linearly the effect of the DANs on valence/speed and other metrics

So this first picture shows graphically how I get the valences contributions for each of the dopaminergic clusters. On the Y-axis you see the lines I used for the modelling and on the x-axis the clusters. This is the expression pattern for all the drivers (split G4 and the dirtier G4s). I also made this expression pattern binary, to avoid the errors I could add by trying to estimate the expression intensity from the literature.

Here below are the results I obtained for one of the metrics. I wont explain to much here because the main result I see is that the results change drastically upon changes in the model. This tells me that there is something wrong there. Since making the expression table binary or weighted, or using a subset of the G4s used should not give me so random values for the dopaminergic clusters.

With this, I am quite stuck and do not know what to do next. Results seem not to show that much. Considering planning another experiment while there is time or continuing analyizing. Comments please!
