% allmyvariables =
% a: {4x1 cell}
% ans: [1x1 struct]
% pm: [1x48 struct]
% res: [2x24 struct]
% results: {{1x3 cell} {1x3 cell}}
% stims: {[1x1 struct] [1x1 struct]}
% train_results: [1x48 struct]
%
% >> only_starting_with_res = ws2struct('res.*')
% only_starting_with_res =
% res: [2x24 struct]
% results: {{1x3 cell} {1x3 cell}}
