Dear Anusha,
this +/-x issue is tricky when you want to exchange data between FSL and
SPM. There is no explicit flip happening at some stage in SPM
preprocessing, instead all images are flipped for display if
defaults.analyze.flip is set to 1. This is of course not honoured by FSL,
and analyze header information is interpreted differently in FSL and SPM.
If you don't want to leave SPM for DTI processing, you could try the
Diffusion II toolbox from the SPM extensions page. This way you would not
have to bother with image orientation issues.
Yours
