description

to create a conceptual structure family from a relational context family. The output is a JSON file that can be opened in RCAviz, a DOT file that contains the graph of the conceptual structure family at the end of the process,TXT files for tracing the size of structures at each step, and traces.csv that contains the formal and relational contexts and other settings used at each step. The input is a relational context family.
