Metadata Stored in the ''info'' Folder
The info folder is a replacement for the BDB-based EMAN2DB folder in the project directory. All information is stored in human-readable and editable JSON files with a .js extension.
quality.js
This file stores user-assigned quality values per-micrograph. The key is the 'basename' of the image file, so the value can propegate through all stages of processing. That is, a file named micrographs/jj1234.mrc would use the key jj1234. Quality values run from 0-9 and may be used in any way the user prefers. They have no absolute meaning to any of the processing software, though there are places where higher will be assumed to indicate better images by whatever standard.
