Burmeister data reader

galactic-io-data-burmeister is a data reader plugin for GALACTIC.

The Burmeister context format uses the extension .cxt.

Each file is structured as follows:

  • the first line consists of a single B;

  • the second line is an empty line (its content is ignored);

  • the third and fourth lines contain the object and attribute count;

  • the fifth line is an empty line (its content is ignored);

  • after that, all objects and all attributes are listed, each on a line

  • finally, the context is given as a combination of . and X, each row on its own line.
