I appreciate your comment Axel!!
I slightly modified my code and it is working now.
However, I have one more question!
My HDR process is like below.
(Please, let me know if there is something wrong in my script.)
=====================================================
Cropping the original HDR image to match the size with the vignetting filter
file
ra_xyze -r -o -u Original.hdr | pcompos -x 4368 -y 2912 - -408 -272 >
Resized_for_Vignetting.hdr
Applying the vignetting filter to the cropped HDRI
pcomb -e 'ro=ri(1) / ri(2);go=gi(1) / gi(2);bo=bi(1) / bi(2)'
Resized_for_Vignetting.hdr Vignetting_Filter.hdr > Vignetting_Corrected.hdr
Resizing the HDRI for glare analysis
pfilt -x 1200 -y 800 Vignetting_Corrected.hdr >
Vignetting_Corrected_resized.hdr
Cropping the HDRI for glare analysis
ra_xyze -r -o -u Vignetting_Corrected_resized.hdr | pcompos -x 800 -y 800 -
-200 0 > Cropped.hdr
Creating the cleaning filter
ra_tiff -r Cleaning_filter.tif Cleaning_filter.hdr
Applying the cleaning filter on the resized HDRI
pcomb Cropped.hdr -s -1000 Cleaning_filter.hdr > Final.hdr
Running the Evalglare analysis
evalglare -vta -vh 180 -vv 180 Final.hdr
=====================================================
After the process above, The header file is like below.

=====================================================
The header file is very long like above after the whole process.
I could run evalglare with the final.hdr. ( It looks OK until now.)
Is the header file is OK for futhur HDRI analysis?
Are there any potential error source in the head?
If I need to modify the head, can you explain a little bit more on vim and
Radiance’s info?
Have a good day!
Best regards,
Jonghoon Kim
