AFQ browser and QSIprep pyAFQ tractometry outputs

I generated pyAFQ tractometry in qsiprep, but was unable to use it with AFQ-browser which requires AFQ or tracula output or manually created text files (The AFQ-Browser data format — afqbrowser 0.1 documentation)

I do not immediately see relevant information in the pyAFQ directory that I could convert. Any pointers would be appreciated.
