How to create a new data set?

[liutianxin0722]

Hello elder
I want to create a new category of data，for example，“bike”. The ID is 02834778
If I use the command ./download_train_data.sh 02834778 , it doesn't work.
So, the question is how to generate the data which is the same as you provide for us like the "chair". How to obtain the camera.mat , depth.png and render.png file? Besides, how do you create files in splits folder , like 03001627.file? 03001627_train.txt?
Thank you
