I am using the Stringdb api to retrieve all the interaction partners of the given input proteins. I am giving a list of input proteins. However, I am unable to know whether the output consists of all the proteins given as input. Eg: if my list is protein A, B and C - ['A', 'B', 'C'] in which the api does not return any output for protein 'B', it does not throw any error. Please tell me how to know if any protein is missing in the output file.
Thanks in advance.
