This command loads a TSV edges file into Graph-tool, and exports it to Graph-tool (.gt) format.

Usage

usage: kgtk export-gt [-h] [-i INPUT_FILE] [-o OUTPUT_FILE] [--directed] [--log LOG_FILE]

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT_FILE, --input-file INPUT_FILE
                        The KGTK input file. (May be omitted or '-' for stdin.)
  -o OUTPUT_FILE, --output-file OUTPUT_FILE
                        Graph tool file to dump the graph too - if empty, it will not be
                        saved. (Optional, use '-' for stdout.)
  --directed            Is the graph directed or not?

Examples

Import a TSV file into Graph-tool, and store the result to disk. We store the statistics to log.txt.

kgtk export-gt -i data/sample_kgtk_edge_file.tsv --directed --log log.txt --out graph.gt 

The file log.txt has the following content:

loading the TSV graph now ...
graph loaded! It has 287 nodes and 287 edges
