- SYSTEM REQUIREMENTS
findDFS.pl - This program runs a dfs over a specified set of sources and relations in the UMLS.
This is a utility runs a dfs over a specified set of sources and relations in the UMLS returning the depth, number of paths to the root, branching factor, leaf and node count.
Usage: findDFS.pl CONFIGFILE [OPTIONS]
Configuration file containing the set of sources and relations to use. The default uses MSH and the PAR/CHD relations.
The format of the configuration file is as follows:
SAB :: <include|exclude> <source1, source2, ... sourceN>
REL :: <include|exclude> <relation1, relation2, ... relationN>
RELA :: <include|exclude> <rela1, rela2, ... relaN> (optional)
The SAB, REL and RELA are for specifing what sources and relations should be used when traversing the UMLS. For example, if we wanted to use the MSH vocabulary with only the RB/RN relations, the configuration file would be:
SAB :: include MSH REL :: include RB, RN RELA :: include isa, inverse_isa
or if we wanted to use MSH and use any relation except for PAR/CHD, the configuration would be:
SAB :: include MSH REL :: exclude PAR, CHD
An example of the configuration file can be seen in the samples/ directory.
Sets the debug flag for testing
Username is required to access the umls database on MySql unless it was specified in the my.cnf file at installation
Password is required to access the umls database on MySql unless it was specified in the my.cnf file at installation
Hostname where mysql is located. DEFAULT: localhost
The socket your mysql is using. DEFAULT: /tmp/mysql.sock
Database contain UMLS DEFAULT: umls
This option prints out the path information for debugging purposes.
Searches up to the specified depth. The default is to search the complete hierarchy
Starts the search at a specified CUI. The default starts the search at the UMLS root node
Returns the number of CUIs above and below this NUMBER
Displays the quick summary of program options.
Displays the version information.
The program returns the following:
1. the maximum depth 2. paths to root 3. sources 4. maximum branching factor 5. average branching factor 6. number of leaf nodes 7. number of nodes 8. root
