Hello,
I want to modify the track config file (i want to modify the parameters in the following screenshot)

Where can i find this file.

Thanks

see https://jbrowse.org/docs/configuration_file_formats.html

the screen you are seeing is essentially the data from your tracks.conf in a trackList.json format with some default values added. you can add them into your tracks.conf or convert to trackList.json and paste that block
