The repo also contains a Python CLI tool, called biomarkers, that can be used to compute the markers for a given Boolean network and phenotype components.

To see the help text and available options of a command call the command with the option -h.
E.g., to see the help text for the command markers-create call biomarks markers-create -h.
The computation of the markers is a two-step process.
First, define a problem file by specifying a Boolean network and the phenotype subspace using the command problem-create:.
$ biomarkers problem-create --problem emt_problem.json --bnet selvaggio_emt --phenotype AJ_b1=0,AJ_b2=0
created json file: fname=emt_problem.json
n_steady_states: 1452
component_names: {0: 'AJ_b1', 1: 'AJ_b2'}
phenotype_subspace: {0: 0, 1: 0}
phenotype_index phenotype n_steady_states
0 0 not {0: 0, 1: 0} 184
1 1 {0: 0, 1: 0} 1268
Instead of specifying a phenotype subspace you may specify the phenotype components:
$ biomarkers problem-create --problem emt_problem.json --bnet selvaggio_emt --phenotype AJ_b1,AJ_b2
created json file: fname=emt_problem.json
n_steady_states: 1452
component_names: {0: 'AJ_b1', 1: 'AJ_b2'}
phenotype_components: [0, 1]
phenotype_index phenotype n_steady_states
0 0 {0: 0, 1: 0} 1268
1 1 {0: 1, 1: 1} 148
2 2 {0: 1, 1: 0} 36
The command creates a problem file in json format.
To compute the markers for a problem file use the command problem-solve:
$ biomarkers problem-solve --problem emt_problem.json --forbidden AJ_b1,AJ_b2 --marker-size-max 5 --markers emt_markers.json

The command creates a markers file in json format.
To export a marker set in csv format use the command biomarkers markers-export:
$ biomarkers markers-export --markers emt_markers.json --csv emt_markers.csv

created emt_markers_counts.tex
The command markers-count counts how often network components appear as markers.
The option --pdf maps the counts onto an interaction graph and --tex export the data as a tex table.
$ biomarkers markers-count -m emt_markers.json --pdf emt_markers_counts.pdf --tex emt_markers_counts.tex
To factorize a marker set use the command biomarkers markers-factorize and specify the markers file.
The option --pdf creates, for each row in the table, a plot of the interaction graph with the marker subsets that make up the factorization highlighted:
$ biomarkers markers-factorize --markers emt_markers.json --pdf emt_markers_factorization
