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

Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"Dear list,
I am trying to glare analysis via HDR images captured by a canon DSLR Camera and sigma fish eye lens.
The procedure that I use was
1. Taking 13 images via gphoto2 +Crontab
2. Creating HDR images in HDRgen
3. Resize
pfilt -x 1433 -y 955 Big.hdr > resize.hdr4.Crop & cleaning mask
ra_xyze -r -o -u resize.hdr | pcompos -x 800 -y 800 - -315 -78 > crop.hdr | pcomb -s -1000 output_masked2.hdr5. Evalglare analysis
echo "VIEW= -vta -vh 180 -vv 180 -vp 0 0 0 -vd 1 0 0 -vu 0 0 1" > output_masked2.hdr
evalglare output_masked2.hdrThe problem is that Evalglare reports errors after the crop process.
error: no valid view specified
(There was no evalglare errors when I test it with the resized image.)
I has checked the luminance values of the HDR in photosphere and it looks OK!
Do I need to use another crop command for evalglare processing?
Please, let me know if you have any ideas.

Content-Type: text/plain; charset=ISO-8859-1Both pcompos and pcomb mess with the HDR header. Also, what you are doing here:
echo "VIEW= -vta -vh 180 -vv 180 -vp 0 0 0 -vd 1 0 0 -vu 0 0 1" >
output_masked2.hdris overwrite HDR image output_masked2.hdr with just the view string.
You need to edit this image in a text editor and put a full VIEW= line
back in. If you're happy using vim, then you could try Radiance's
vinfo.Regards
