NAME

       go-dag-summary - summarises an ontology

SYNOPSIS

         go-dag-summary ontology/gene_ontology.obo

DESCRIPTION

       Summarises an ontology

ARGUMENTS

       -e ERRFILE

       writes parse errors in XML - defaults to STDERR (there should be no parse errors in well formed files)

       -p FORMAT

       determines which parser to use; if left unspecified, will make a guess based on file suffix. See below
       for formats

   -use_cache
       If this switch is specified, then caching mode is turned on.

       With caching mode, the first time you parse a file, then an additional file will be exported in a special
       format that is fast to parse. This file will have the same filename as the original file, except it will
       have the ".cache" suffix.

       The next time you parse the file, this program will automatically check for the existence of the ".cache"
       file. If it exists, and is more recent than the file you specified, this is parsed instead. If it does
       not exist, it is rebuilt.

OUTPUT

       One row per ontology

       Each row has the following columns

       input filename
       total no of terms
       total no of relationships
       total no of paths
       avg no of paths per term (p/t)
       maximum no of paths for any term
       ID of term with maximum no of paths
           NOTE: obsolete terms are not included
