Tobii Pro Studio Tobii Pro
If I run my calibration in another application, such as E-Prime or the "One-Eye Calibration Tool," can I disable the calibration in Tobii Pro Studio?

In order to disable the calibration, follow these steps:
1. Ensure that Tobii Pro Studio is not running
2. Open the file called "ApplicationSettings.xml" using a text editor, e.g. Notepad. The file is located at: 
c:\Users\{UserName}\AppData\Local\Tobii\Studio\
3. Before the last row in the file (which says </ArrayOfDictionaryEntry>), add this text:
<DictionaryEntry>
<Key xsi:type="xsd:string">Bool_CalibrationByExternalTool</Key>
<Value xsi:type="xsd:boolean">true</Value>
</DictionaryEntry>
4. Save and close the file

To enable it again, follow these steps:
1. Ensure that Tobii Pro Studio is not running
2. Open the file called "ApplicationSettings.xml" using a text editor, e.g. Notepad. The file is located at: 
c:\Users\{UserName}\AppData\Local\Tobii\Studio\
3. Locate the rows in the file which says:
<Key xsi:type="xsd:string">Bool_CalibrationByExternalTool</Key>
<Value xsi:type="xsd:boolean">true</Value>
4. Change the text true to false
5. Save and close the file
6. The calibration is now enabled
