I am a new bird，please help me. Thanks a lot.
I used other datesets to run，there has Focal length，before running <bundler list.txt --options_file options.txt> it shows the errors like thoes below.

I use the cygwin run it .After I edit the list.txt(there have two list.txt(one is in result file,the other is in prepare file) and I edit both of them).
How does this code (bundler list.txt --options_file options.txt) run？？？-- --

It looks like sift is not running correctly and giving segmentation faults. Any idea why that might be happening? One possibility is that if your images are very high resolution, I think sift might not be happy. Noah

so how to fix that?and how to change the resolution of images?thank you.

Try to run the sift binary on the provided examples, such as ./examples/kermit. If the program executes successfully, then probably something wrong with your images. Otherwise, the sift binary is not working properly on your machine.

Run file sift and uname -a to see if the binary exec is compatible with your system. If sift is not working properly (on images such as book.pgm), try this fix:

sudo apt-get install --reinstall libc6-i386
sudo apt-get install libgl1-mesa-glx:i386 lab-core

…

Yes. From sift:

sift: util.c:330: ConvHorizontal: Assertion `cols + ksize < 8000' failed.

There is a limit on the image resolution.

I had the same problem when I ran very big jpg files (no problem for /kermit). May I know how to fix it? BTW I use Cygwin to run the code
