[IGSTK-Users] Attaching Tracker Tool to Tracker

[Rafael Palomar]

Hi Patrick, you are right.

It seems that I had not configured the tool properly so when I had tried to
attach it to the traker, I had got the error. Now that the tool is well
configured the attachment is correct.

Thank you.

Regards,
Rafael Palomar.
