FindDQE

When I run the software FindDQE.exe, but some error message like this:

*** Error in `finddqe.exe': free(): invalid next size (normal): 0x0000000002260d20 ***

Program received signal SIGABRT: Process abort signal.

It is not entirely clear what this error message means but could it be that you were running out of memory on the machine you ran FindDQE on? The long run time suggests that it might have used the swap file on the disk. Please check if you have sufficient memory to run the program.

Hi Niko,

I use top to monitor the program. finddqe only use 4.8% of the memory.

even though the error message, the FindDQE can run to the end. but the DQE vlaue too small

my CCD is the same type US4000, same to yours. my dose is 22.8e/pixel.

what else I need to pay attention?
