This is my code to read c3dfiles of 5 subjects en their measurements.

function read_data_stair_rise
aantal_proefpersonen = length(dir('data_stair_rise'))-2;
for welke_pp=1:aantal_proefpersonen %first forloop for 5 subjects
  myFolder =sprintf('data_stair_rise/pp%c',num2str(welke_pp));
  %bepalen van het filepatroon om het later te kunnen inlezen 
  filePattern = fullfile(myFolder,'*.c3d');
  c3dFiles = dir(filePattern);
for i_testen=1:length(c3dFiles); %for their c3dfiles
  baseFileName = c3dFiles(i_testen).name;
  fullFileName = fullfile(myFolder, baseFileName);
  [VideoSignals,VideoSignals_headers,AnalogSignals,AnalogSignals_headers,AnalogFrameRate,VideoFrameRate] = read_c3d_file(fullFileName); %function to read c3dfiles
  data_stair_rise(welke_pp, i_testen).VideoSignals = VideoSignals;
  data_stair_rise(welke_pp, i_testen).VideoSignals_headers = VideoSignals_headers;
  data_stair_rise(welke_pp, i_testen).AnalogSignals = AnalogSignals;
  data_stair_rise(welke_pp, i_testen).AnalogSignals_headers = AnalogSignals_headers;
  data_stair_rise(welke_pp, i_testen).AnalogFrameRate = AnalogFrameRate;
  data_stair_rise(welke_pp, i_testen).VideoFrameRate = VideoFrameRate;
end
end
end

But I don't need some tests. So I created this code:

if ~( ((i_testen == 4) && (welke_pp == 3)) || ((i_testen == 4) && (welke_pp == 4)) );
end

But where should I place this in my function so that these tests aren't included?

Sam - as your conditions depend upon i_testen and welke_pp, then this if statement should be the first line of your inner loop when you know the values for both of these indexing variables.
