Hello @jeylau , I created this function because I had originally created a dataset with 14 body parts. Later I decided to make another project, where I kept the body parts of the previous project (these 14) but added new body parts. As I already had many frames with the 14 labels, I wanted to be able to transfer them to the new project, and only have to label the new body parts. For this, I created a new project, with all the body parts I was interested in (old and new), I kept the “labeled-data” folder of the old project, and I used the adapt_labeled_data_to_new_project function to add the new body parts to the .csv and .h5 files, so I could label the new bodyparts from the GUI.

I didn't manage to do this by adding the new body parts to the config file, but I may have skipped a step.
