`animal_weight_prior` metadata field is being erroneously populated with animal's base (pre water restriction) weight

[dougollerenshaw]

Currently, the Dynamic Foraging software is erroneously populating the animal_weight_prior field with the animal's base weight, which is the weight of the animal prior to the beginning of water restriction (and which is used to calculate the water supplement necessary to keep the animal at its IACUC-protocol-required fraction of base weight).

However, this field in the metadata is meant to capture the animal's pre-session weight. See here: https://aind-data-schema.readthedocs.io/en/latest/acquisition.html#acquisitionsubjectdetails

The Dynamic Foraging software should be modified to fix this. If the pre-session weight is not available, this field should be null in the metadata.

@micahwoodard could likely weigh in on this

I'm pretty sure @XX-Yin or @alexpiet wrote the code for this so they would be good to loop in. Looking at the UI and codebase, it doesn't look like the animal's pre-session weight is recorded anywhere? I could be missing it though.

In this case we should be setting the animal_weight_prior to None correct?

From what I understand, you're correct. This information isn't being recorded at all.

Correct.

okay i can put in a pr

[galenlynch]

Do people weight the animal before hand? I don't.

[micahwoodard]

@galenlynch I don't think so but @ellahiltonvano to confirm. I set the animal_weight_prior to always be None since that information is not provided anywhere I could find in the software

@galenlynch based on this discussion it seems like no one is recording pre weight https://github.com/AllenNeuralDynamics/aind-scientific-computing/issues/95#issuecomment-3675752779
