How to train on another dataset

I would like to know how can we train on another dataset , and how to generate the all_98pt.txt file. I tried but it showed me an error.

It seems that it does not need the actual heapmaps in the all_98pt.txt. The boundaries are generated during the training. The heatmaps in the all_98pt.txt files are not loaded in the training scripts.
