How to pre-process and extract the Nvidia hand Gesture dataset?

There are 31 files named: 

                          nvGesture_v1.7z.001
                         to nvGesture_v1.7z.031

I am looking to extract these files to video format. Since these files are zipped in .7z format. I tried using 

                          cat nvGesture_v1.7z.0?? | 7za x

or

                          cat nvGesture_v1.7z.0?? | 7za e

but in both cases I get error:

                            Error:
                            Incorrect command line
Solution

  • Ok, 2 min after I posted the comment on the original questions, I think I got what you need:

    7z x nvGesture_v1.7z.001

    It will unzip the videos in the original folder structure: Video_data class_01 subject1_r0 (etc)
