read all .exr files

Hi, I'm using this user-defined function (exrread) to read .exr file but how can I read all of my .exr files at once? I try to use dir and put .* after the name of the file but I still couldn't get the list of all my files. k=exrread('file.exr'); This k value will be used to calculate MSE.

dinfo = dir('*.exr');
nfile = length(dinfo);
for K = 1 : nfile
  thisfile = dinfo(K).name;
  try
    data = exrread(thisfile);
    fprintf('Was able to read file "%s"\n', thisfile);
  catch
    fprintf('Was not able to read file "%s"\n', thisfile);
  end
end

Hi, what I mean is I have these coding:

F1= exrread('beerfest_lightshow_01_001591.exr');
F2= exrread('001.exr');
MSE=MSE1(F1,F2);

but that only calculate the MSE for one image. I have 94 images, what should I put to make a loop on this system in order for me to get the MSE for all 94 images in one run? thanks

Is each of the 94 images to be compared to each of the other 93 images, for a total of (93*94)/2 MSE values calculated? If not then which image is to be compared to which other image?

I have 94 compressed images to be compared to their respective original images.

Are the compressed files and the original files in different directories? Given the name of a compressed file, how can you determine the name of the original file (or the other way around) ?
