Hi, Although peripheral to most developers using the CCTBX I would like to announce an extension library for SQLite that allows creating histogram tables, tables of average values of histogram bins as well as tables of ratios between histogram bins from existing SQLite database files. https://github.com/Oeffner/SQLiteHistograms In our group we often use SQLite databases for statistical analysis of results. This extension library permits you to create histograms of an existing table with one line of SQL.
