In the data for task 2, there is - for example, a stimulus definition "AP752" consisting of 5 components: 100; 237; 420; 434; 531. Each of these components are in turn either neat, or diluted in a solvent. For example, 100 is 0.001 weight fraction in pg, while 237 is 0.3 weight fraction in DEP. How are these 5 combined in the mixture? Are they equal parts? So other relative ratio? Since concentrations matters (purpose of task 1) I struggle to see how to make predictions for task 2 if this is not specified. Am I missing something?

I completely agree with you. I apologize for not explaining these details more clearly earlier. Thank you so much for your time, participation, and the outstanding work you’ve contributed!
Thank you @Songxuebo - it also my own mistake for only getting to task 2 today that I didn't ask this earlier, but isn't this really critical information to be able to answer the task 2 challenge? I could not find this information communicated in the Task 2 description, nor from what I can see in the other discussions.
Hi, Thanks for your question! When preparing the mixtures, each individual molecule is combined in equal volumes.
