Exporting tract stats on multiple TRK files

[Artur Vetkas]

Hi!

Is there a way to efficiently export stats on multiple .trk.gz files through console? I tried the same approach as when merge but it did not work.

--action=ana --source=HCP1065.1mm.fib.gz --tract=AC.trk.gz,AF_L.trk.gz --export=stat

Thanks in advance

Could you post the console output?

There might be a hint why it didn't work

The code i used is: --action=ana --source=HCP1065.1mm.fib.gz --tract=AC.trk.gz,AF_L.trk.gz,AF_R.trk.gz,AR_L.trk.gz,AR_R.trk.gz --export=stat

The console loads of the tracts and show the count, but runs the statistics and the outputs only the first.

Thank you for sending the details.

The quick solution is to call the command multiple time, with each for each track.

Best
