Hi FSL experts.
I have run my tractography analysis on the majority of my participants and I noticed that I am missing DTI data (FA, RD, MD) for many of my participant's tracts or I am only getting DTI information for ~40% of the tracts (note: the tracts with DTI information are not consistent across all participants).
I have maintained the standard protocol for all analysis and was wondering if anyone had any insight into why I may be loosing data. I think the problem is that the tracts are not being located, and therefore DTI information can not be calculated for those tracts. Does anyone have any suggestions on the most standard way to change my analysis so that I obtain more information - or should I just work with that I have?
Below is some info on my analysis......
I have 12 directions in my data
The tracts I am looking at:
Superior Longitudinal Fasciculus
Inferior Longitudinal Fasciculus
Inferior Frontal-occipital fasciculus
Thank you, thank you, thank you for any help :)
I really appreciate that there is a wonderful forum like this, and hopefully when I know enough about FSL I can help other people out.
