Hi!
Have you checked in the module data if the Tracker was added?
Have you seen the transformation changed?
In OpenIGTLinkIF you have to set Tracker(POSITION) as locator source.

Today I was not able to connect on Slicer default port 18944, so I defined a
different port - 10001.
You have to define port before activating server and make sure you press
return  after entering port number, otherwise it goes back to default :-)


I have Slicer 3.41.0 and 3.6 RC2 1.0
