just convert the data into a format FSL can read and create a proper 4D-file (where the fourth dimension is your bvecs so to say). If you have multiple acquisitions the image reconstruction of your scanner may either spit these out averaged or (/and) seperately. In the latter case, you may want to create the appropriate average yourself (to increase SNR). Finally, it is always a good idea to look at the data you have acquired, i.e. by using fslview (here, the movie option comes in handy!). This may give you the option to discard volumes afflicted from strange artefacts. Then, just go ahead for ECC.

Betreff: [FSL] Pre-Processing in FDT
Using FDT, there is one recommended processing pipeline which can
be found on the website
The first item is the scanner-specific pre-processing.
In our Lab, we use Siemens Sonate 1.5T scanner to acquire
diffusion weighted images. I would like to ask your suggestions about the
necessary procedures for the pre-processing (besides of the motion
correction and BET) ?
Thanks in advance
