Can you describe with GT dataset did you try to use?
Can you share here the command line you are using?

Thanks for your attention.

i use Herz-Jesus-P8

./openMVG_main_evalQuality
-i E:\Academic\sfmevaluation\HJ\Herz-Jesus-P8
-c E:\Academic\sfmevaluation\Herz-Jesus-P8\reconstruction\sfm_data.bin
-o E:\Academic\sfmevaluation\Herz-Jesus-P8\evaluation

You can take a look to the scripting that exists here https://github.com/openMVG/SfM_quality_evaluation
As I remember the script is still working.

Sorry , i changed the order after understanding the script.
but error still occured,and contents also changes.
"
The provided GT directory does not have any *.camera file.
Error: Failed to Load Ground Truth!
Cannot initialize the GT dataset.
"
But i have downloaded file of gt_dense_cameras,and it has *.camera

the command line is :
./openMVG_main_evalQuality
-i E:\Academic\sfmevaluation\HJ\Herz-Jesus-P8\ gt_dense_cameras
-c E:\Academic\sfmevaluation\test02\outGlobal\sfm_data.bin
-o E:\Academic\sfmevaluation\test02\outGlobal\stats

Does your image and camera have the same extension (jpg/jpg, or png/png)?

Also I noticed a space before the p8/ and your folder / gt... be sure you have the right path-i E:\Academic\sfmevaluation\HJ\Herz-Jesus-P8\ gt_dense_cameras=> E:\Academic\sfmevaluation\HJ\Herz-Jesus-P8\gt_dense_cameras

Thanks a lot. I have solved it.
But I have a question, How can I get this results?

Should I add images one by one?

The script generates the value, so you have to keep the values and put them in a plot
