I ran an experiment on a cluster, and noticed 1/10,000 MAT files gave a "cannot read file" error when collecting results. I downloaded the MAT file and confirmed the error. I then reran the script that generated the MAT file, and was given the same error on the new MAT file. Once again, I download the MAT file onto my local machine. I noticed despite the error, MATLAB successfully loads variables into the workspace and they seem to be working fine.
I suppose I shouldn't be compaining but I want to know what is going on....
Obtaining the header from the following code outputs
fid = fopen(fn, 'r');
header = fread(fid,120).';

Note that I restarted MATLAB and cleared all multiple times, to ensure the variables were not in my workspace beforehand.

There could be a possibility of the file being corrupted. For further analysis, you can use the MATCAT tool , which is available on File Exchange
