Clarification on list of images used by Bundle2Info

[mtmarsh2]

In the documentation, it says to use a file called 'list.txt' which stores the names of the images used. Is this file supposed to have just an image name on each line? Bundler produces a 'list.txt' file, but that file has more information than just the image name one each line. I'm getting the warning: "Trying to load the descriptor for feature from camera in keyfile but only 0 in keyfile."

"Suppose that you have a structure-from-motion reconstruction computed by Bundler, located in the directory BUNDLE_DATA, where the output generated by Bundler can be found at BUNDLE_DATA/bundle/bundle.out and the list of used jpg images is stored at BUNDLE_DATA/list.txt."
