Question about preprocessing pku dataset

[VinnyCSY]

Hi,

I have a question about preprocessing stage in '/tools/data_gen/pku_gendata.py'.
According to the code, the filename of video should be in format 'FxxxVxxxCxxx.txt'.
However, the skeleton files have name in format 'xxxx-V.txt' which V=L/M/R.

The image below is from the link https://github.com/ECHO960/PKU-MMD

This dataset seems to be in sequence of action clips.

Is the format of videos changed with the version you've used?

Thank you.
