Check if your file filename_2 exist in your folder

Seems for me it has more to do with
for run= 2:2
and
for run= 1:1

Use the debugger and check what are the value of
run
and
ic
And what if you use only the command without any for loop.

Not really sure - maybe it's a conflict between using the command line version of load and the function version (do you even know the difference?) Do you really have an equal sign in the filename, and no extension (such as .mat) for it, and that filename_2 is the actual filename and not the variable name? Anyway, assuming that's the case, try this more robust code:
for run = 2:2
for ic = 11:12
if ic == 11
fullFileName = fullfile(pwd, 'filename_2');
else
fullFileName = fullfile(pwd, 'filename_2_eps=1');
end
if exist(fullFileName, 'file')
load(fullFileName)
else
message = sprintf('Error: file not found:\n%s', fullFileName);
uiwait(warndlg(message));
end
end
end
Or maybe it's the fact that you're using run as a variable name but MATLAB considers it a built-in function name (so you should not use run as a variable name, just like you shouldn't use for, while, sprintf, load, etc. as variable names either).

I don't know what the second sentence means. What does "not right" mean to you? Also, there were 7 questions in my prior comment and you answered only 2 of them, at most.

Your loop is overwriting X0in on each iteration, it appears.
