Hi all,
The below code is generating an error :
The code used here is:
%BATCH MODE
files = dir('C:\Users\Deakin Uni\Documents\MATLAB\a');
fNames = {files.name};
%for each file
for k= 1: length(fNames)
% extract file name
fName = ['C:\Users\Deakin Uni\Documents\MATLAB\MAX', fNames{k}];
[XDATA, TIMESTEPS] = importfile(fName);
a1 = XDATA - mean (XDATA);
plot(TIMESTEPS, a1);
[peakvals,peaklocs] = findpeaks(a1, 'minpeakdistance',50, 'minpeakheight', 0.00001);
peaktime = TIMESTEPS(peaklocs);
createfigure4(TIMESTEPS, a1, peaktime, peakvals)
saveas(gcf, 'chaitu.fig')
end
The error here is: Error using xlsread (line 132) XLSREAD unable to open file 'fName'. File 'fName' not found.
Error in importfile (line 36) data = xlsread(workbookFile, sheetName, sprintf('A%d:B%d',startRow(1),endRow(1)));
Thanks in advance

Presumably, the cause is that for some value of k,
['C:\Users\Deakin Uni\Documents\MATLAB\MAX', fNames{k}]
does not resolve to a string that corresponds to a file name in that directory.
I suggest you display the name of each file as you try to access it, and that should lead you to the specific file name that is problematic.

Nothing stands out to me (after admittedly not very intense scrutiny). Are you familiar with the ability to enter debug mode? I suggest you use that to step through your program line-by-line from k==1, and see if the values of the variables are what you expect them to be. This should give a clue about what went wrong.
