Tools/ecl_ekf/process_logdata_ekf.py could not find estimator_states data

Hello,

When trying to use the python script to check the ekfs performance as described in how do I check the ekf performance, it always returns with an error stating:

could not find estimator_states data

Do I have to manually enable the logging of estimator_state data, because in my understanding this should have been enabled by default.

Thanks in advance!
