The software package 4ti2 is a suite of command-line tools for addressing algebraic, geometric and combinatorial problems on linear spaces.
The main concept of 4ti2 remains the same: a project is defined via a file foo[.mat] containing the problem matrix. Related sets such as Graver basis or Markov basis are put into foo.gra and foo.mar, respectively. Input files and output files usually contain a matrix or a list of vectors (written as a matrix) in a standard encoding such as 2 4 1 1 1 1 1 2 3 4 There are only few exceptions, for example in a file foo.vars containing user specified variable names: 3 a b x
