Dear freesurfer experts

I am a beginner in DWI data processing and my question may be absurd, if so, I apologize in advance.

I am using TRACULA for the analysis of my DWI data. Reviewing the outputs of the statistics for the FA index I realized that some of these are greater than 1. Considering that FA oscillates between the values 0-1, how is this possible? 

I send to you in attached the .txt with the average FA values for the Forceps Minor where the "anomalous" values can be observed.

Thanks in advance

Best regards
