Directory arrangements cause errors. vel_data not reading

[LiChiehLin]

When adding strong motion or GNSS data to the inversion based on previous auto model result, an error will show that the program is not reading vel_model data in NP/ directory.
The tutorial worked fine and the directory is as follows:
/home/user/Documents/FF-env/20150916225432/ffm.0/NP1.1
Mine is (2 folders more than the tutorial):
/home/user/Documents/Events/20240403Hualien/Slip_inversion/20240402235811/ffm.0/NP1.1

This error could be fixed by arranging the directories shorter, like this:
/home/user/Documents/Slip_inversion/20240402235811/ffm.0/NP1.1

(When I try adding static GNSS data)

I assume the path search is hard-coded in the corresponding python script so this happened. Also, when I try to troubleshoot this, I deliberately make my NP/ folder name ridiculously long and the routine did not print out the exact folder name I fed in. It was truncated to 6 characters.
