NAME

findDFS.pl - This program runs a dfs over a specified set of sources and relations in the UMLS.

SYNOPSIS

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

Usage: findDFS.pl CONFIGFILE [OPTIONS]

INPUT

Required Arguments:

CONFIGFILE

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.

Optional Arguments:

--debug

Sets the debug flag for testing

--username STRING

Username is required to access the umls database on MySql unless it was specified in the my.cnf file at installation

--password STRING

Password is required to access the umls database on MySql unless it was specified in the my.cnf file at installation

--hostname STRING

Hostname where mysql is located. DEFAULT: localhost

--socket STRING

The socket your mysql is using. DEFAULT: /tmp/mysql.sock

--database STRING

Database contain UMLS DEFAULT: umls

--debugpath FILE

This option prints out the path information for debugging purposes.

--depth NUMBER

Searches up to the specified depth. The default is to search the complete hierarchy

--root CUI

Starts the search at a specified CUI. The default starts the search at the UMLS root node

--level NUMBER

Returns the number of CUIs above and below this NUMBER

--help

Displays the quick summary of program options.

--version

Displays the version information.

OUTPUT

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
