Not saving trajectory file

[immuhammadadil]

GSLAM is loading and processing frames but not showing it in panel in GUI.
It just prints the following details:
Play thread stoped.

------------------------------------ Timer report ------------------------------------
FUNCTION #CALLS MIN.T MEAN.T MAX.T TOTAL
