Hello, I've tried adding both "--eval-log" and "--eval-log frame_trajectory.txt" to the command, but I couldn't find the corresponding trajectory file after running it. Can you please help me? Thank you.

You can turn the if(eval_log) statement off so that it forces you to write the results to files.
I have tried that and the frame_trajectory.txt appears in the repository directory.

@C-H-Chien,I still couldn't find the corresponding trajectory file after running it.

I understand now; the results are generated only after closing the visualization window.

Glad it works for you now. The file is written right after SLAM.shutdown(); which requires closing the visualization window.
