Hi there, thanks for the feedback! The 2 examples in the write-up are: 1) Molecular Weight: weighted sum across amino acid sequences, using amino acid weights defined in [1] 2) List Concatenation: aggregate lists of added resistances (like ['Ampicillin', 'Kanamycin']) across itself and all ancestors
These are simple, and can be expressed as formulas in Excel or functions. They take < 0.5 s.
A more complex biochemical property for antibodies that can't be as easily expressed in Excel is isoelectric point ([2], see example BioJava implementation at [3]). It requires a binary search, but the search space is constant so usually these calculations finish < 20 s.
Since our implementation is in Python, we can wrap the function in try/catch and, in the catch block, log the error and set the failed computation status.
