Code Block
languagenone
cd \cTAKES-2.6

Linux:

Code Block
languagenone
cd /usr/bin/cTAKES-2.6


Note

cTAKES_HOME must be your current directory unless you are skilled at setting paths on your machine.

2. Start the CAS Visual Debugger by running this command:
Windows:

Code Block
languagenone
runctakesCVD.bat

Linux:

Code Block
languagenone
runctakesCVD.sh

The application may take a minute to start on slower hardware.

3. An analysis engine (AE) needs to be loaded in order to process text.
Use the Run-> *Load AE*menu bar command. Navigate to the file

Code Block
languagenone
<cTAKES_HOME>/cTAKESdesc/cdpdesc/analysis_engine/AggregatePlaintextProcessor.xml

Click Open.
