Hi HYZ,
I understand that you want to open a .seq file. For handling .seq files, please refer to the videos section of the documentation of Piotr toolbox, which you can find here: https://pdollar.github.io/toolbox/
The documentation provides details about the available functions, which you can utilize according to your needs.
To verify whether Piotr's Toolbox is installed, you can run the following command in MATLAB, or any other command from the toolbox:
>> ccc
If this command throws an error, it suggests that the toolbox is either not installed or its path has not been added to MATLAB.
Additionally, you might find the following MATLAB Answer relevant to your situation helpful:
Hope this helps!
