     RD=load(Filelist(i).name);
     GO=load('Chlis.txt'); 
    nrec=size(RD,1);
     nchl=size(GO,1);
   for i = 1:nrec,
     for j = 1:nchl,
        RD(i,j)=RD(i,j)*GO(j,2)+GO(j,3);
     end 
   end

Ah i see now,

RD=load(Filelist(i).name);

should probably be

RD=load(fullfile(path_01, [Filelist(i).name]));

and

filename_out = fullfile(path_02, [Filelist(i).name]);

should probably be

filename_out = fullfile(path_03, [Filelist(i).name]);
