Enable "Process fit file messages"

Questions & Help
1

Hi David,

I am developing a custom circular chart for Garmin Cycling Dynamics (Power Phase left/right). I have the FIT data, but I need to parse the arrays into start/end custom streams. Could you please enable developer access / custom JavaScript streams on my account so I can check ‘Processes fit file messages’?

There is no need to activate anything. You can process fit files. Just click the appropriate checkboxes

For me the option is dissabled as soon as I select a Fit Field

BTW I want to achieve splitting the Fit File data for power phases from 4 colums into 8 separate streams. I need to have start and end angles for the power phases as a stream to calculate and draw Cycling Dynamics Diagrams.

This creenshot from Fitfileviewer shows that those values are actually not single values but pairs stored in an array that I need to separate.

So either you select a record field OR you want to create a script from the fit data, then tick the checkbox and aggregate the data in the script tab

You where spot on. I need to leave the Fitfile Field empty. Now it works :slight_smile: Thank you very much!!!
