Setting environment variables
Set the following environment variables in your profile:
• TGREP2_CORPUS - Set this to the TGrep2 default corpus. If you run TGrep2 without a
corpus argument, it will run on this corpus.
• TGREP2ABLE - Set this to the directory that contains the TGrep2 corpora.
• TDTlite - Set this to the directory that contains the TDT scripts.
• TDT_DATABASES - Set this to the directory that contains the TDT databases.
In addition, add the TDTlite script directory to your PATH variable. For example, this is
an example of what to add to your profile (file .bash login, .bash profile, or .profile in your
home directory) if you’re operating in a bash.
TGREP2ABLE="/corpora/TGrep2able"
export TGREP2ABLE
TGREP2_CORPUS="$TGREP2ABLE/swbd.t2c.gz"
export TGREP2_CORPUS
TDTlite="/corpora/TDTlite/"
export TDTlite
TDT_DATABASES="/corpora/TDT/databases/"
export TDT_DATABASES
PATH="$HOME/bin:$PATH:/corpora/TDTlite"
In a C shell, add the following to your profile (file .login in your home directory) instead:
setenv
setenv
setenv
setenv
setenv

TGREP2ABLE /corpora/TGrep2able
TGREP2_CORPUS $TGREP2ABLE/swbd.t2c.gz
TDTlite /corpora/TDTlite/
TDT_DATABASES /corpora/TDT/databases/
PATH $PATH:corpora/TDTlite
Creating a project
Start by creating your project directory. If you are planning on using the run script included
in the TDTlite Tools to create your database, you will need to create the following directories
in your project directory:
• data is the output directory for run’s calls to TGrep2, i.e. this is where the TGrep2
output files (with the extension .t2o) will be stored in ‘data/corpus name’.
