Dear Freesurfer and DTI experts,

I will start some analyses with DWI data, but I have some doubts about it:

1) I have data with 5 different acquisition protocols, so, I'm not sure if the standard pre-processing protocol (like eddy-current compensations the reorientation of the vectors and the intra-subject registration) can be applied to all images equally or if I do need to set any specific parameters for each acquisition protocol?

2) Does your method have any tool to check that the vectors are good, before or after fitting the tensors?

Many thanks in advanced,
Gabriel
