Replaying a logfile
The
Replay Logfile
window can be used to replay a previously created logfile. It has the follow-
ing options:
•
Logfile
: The logfile that will be replayed.
•
Hardware Type
: The hardware type of the device used in the logfile. This is necessary
to determine to correct initial orientation in the tracker. Only required when replaying
a csv file.
•
Sampling Rate
: The sampling rate used in the logfile. This is used to calculate the
Read
Interval
(below) and for calculating FFTs. Only required when replaying a csv file without
information header.
•
Number of Nodes
: The number of nodes in the logfile. This is used to calculate the
Read
Interval
.
•
Read Interval
: The interval in microseconds at which samples in the logfile are added to
the plots. The initial value is determined by the
Sampling Rate
and
Number of Nodes
,
but the interval can be manually adjusted. During a replay, the slider can be used the
change the speed of the replay.
•
Rewrite Replay Log
: The logfile will be rewritten to a new file (same name, with
-replay
appended), and the orientation (Euler angles and/or quaternions) will be (re)calculated.
A replay is started with the
Play
button, and stopped with the
Stop
button. During the replay,
it can be paused with the
Pause
button. The buttons in the toolbar can also be used to control
the replay. Replays are added to the drop-down menu of the
Connect
button. Finished replays
are removed from the drop-down menu when the
Available...
option is used.
