function degenerationAll(caseID, musclesList)
%%DEGENERATIONALL fills the Shoulder database with muscle degeneration measurements
%
% This function fills the Shoulder database with the muscle degeneration
% values of the case given as input. The measurements are stored in a XLS
% file.
%
% USE: degenerationAll(caseID, musclesList)
%
% INPUT caseID: Case IDs for which you want to compute muscle degeneration.
% Cell array that stores the case IDs as a char in the form 'P###' or
% 'N###' (starts with "P" or "N" followed by 1 to 3 digits).
%
% musclesList: List of muscles which you want to compute muscle
% degeneration. Cell array that stores each msucle name as a char.
%
% REMARKS The muscle values are saved in the muscles.xls file.
