Evalutation Scripts, RMSE 0% on all sequences, trajectory file consists only of small number of frames

Hi, I have two issues with the code base.

1. I have got to compare accuracy of ICE-BA with some different front-end. But I could not find any evaluation script for computing ATE.
2. I went through the code and found that back-end consists of RMSE calculations. However when I run it, I always get zero LBA and GBA error.

I get the following output:

Kindly provide solution as soon as possible as we need to meet a near deadline.

Thank you

Reproduce ../bin/back_end ../config/config_of_stereo.txt and inspect the generated RMSE_stereo/MH02_1.txt alongside the trajectory inputs under the MH02 paths shown. Trace the evaluation entry point for the missing ATE calculation and the reported LBA/GBA values; done means an ATE evaluation is available and the run no longer produces an unexpectedly short trajectory or all-zero errors.
