Hi Matt
Thanks for your reply. I too am concerned about these potential
limitations. I still am going to go beyond the standard FA and ADC
measurements to gain some experience with TBSS and a feel for the pitfalls
such as this as I feel it will benefit my planning of my next DTI
acquisition.
I think I am going to change the order of my processing so that eddy
correction is done before downsampling the data so that the FA maps
generated by FSL are available for comparison to those done with
DTIStudio. I still have not had a response as to the impact of the order
of these steps.
Cheers,
Deryk
PS Keep up the good work you are doing imaging the arcuate fasciculus.
Your most recent paper in Cerebral Cortex will inform the interpretation
of the results of an MEG study I am completing.
