KFA calculation

[rosella1234]

When I try computing DKI metrics with dipy, everything works for FA;RD;AD;MD and KM,RK;AK , whereas KFA gives the following error:

KFA = dkifit.kfa
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'DiffusionKurtosisFit' object has no attribute 'kfa'

Thank you,
Rosella

Hi Rosella - thanks for reporting. How did you install DIPY? What version are you running?

The reason I ask is that this feature is a recent addition, so you might need to upgrade your installation (e.g., by running pip install dipy --upgrade)

I have upgraded dipy and the current version is 0.16.0 . Is that the most recent version? thanks, Rosella Il giorno mar 18 feb 2020 alle ore 14:34 Ariel Rokem < notifications@github.com> ha scritto:

• The most recent version is DIPY 1.1.1. It works only on python 3
• the version 0.16.0 is the last version on python 2

Are you using python 2 @rosella1234? If yes, you will have to update your environment and use python3 because python2 is not anymore maintained and all packages are moving.

Ok I have set my python 3.4 version as default and I will now install dipy latest version. Thanks, Rosella Il giorno mar 18 feb 2020 alle ore 17:20 Serge Koudoro < notifications@github.com> ha scritto:

I recommend you to set it up for python 3.6 or more. Python 3.6 will stick around for a long time.

On the opposite, python3.4 is not anymore maintained so DIPY can not rely on it. Furthermore, they will stop the maintenance of python 3.5 this year.

I believe the question has been answered, so I am going to close this. Feel free to reopen if you still have a follow-up.
