Parfor Loop Error Using imwrite
Hi there,
I am trying to use a parfor loop which includes code which generates a RGB image and then saves it using the "imwrite" function within the parfor loop. It runs for a certain period of time and then randomly gives me the following error:
"PNG library failed: Could not open file..
Error in imwrite (line 566)
feval(fmt_s.write, data, map, filename, paramPairs{:});
Error in HEATMAP_SCRIPT (line 65)
parfor i = 2:N"
The error seems to occur at random, sometimes occuring at 20% completion of the parfor loop or sometimes 30% etc. Any suggestions as to why this may be happening and how I can get around this?
