function muscles_results = degenerationAll3D(caseID, musclesList)
%%DEGENERATIONALL3D returns a structure array containing muscle
% measurements for each case ID entered as input and 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, for all CT slices available.
% The measurements are stored in a XLS file and in the MySQL database.
%
% USE: degenerationAll3D(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.
%
% OUTPUT muscles_results: structure array containing fields 'Case_ID',
% and structure array field "muscle name" with muscle
% measurements for each slice for the current patient: 'Stot',
% 'Satrophy', 'Sinfiltration', 'Sosteochondroma' and
% 'Sdegeneration', 'atrophy', 'infiltration', 'osteochondroma'
% and 'degeneration'
%
% REMARKS The muscle values (ratios) for all available CT slices are
% saved in the muscles.xls file and in the shoulder MySQL
% database.
