Dear Mark and all,
Thanks again for your keeping me informed. Now I want to know how
to prepare input 4D image.
I tried in the last hours and failed to get a result.
As you know the command line of eddy current correction is as
follows.
eddy_correct <4dinput> <4doutput> <reference_no>
But I met troubles in preparing 2D input images. Does anyone know
how to convert a series of dicom images to 4D images which FSL required?
Is there a file which introduce in detail the usage of eddy_correct?
Thanks.
All the best.
J.

Dear Jiali,
There is a tool called eddy_correct which you can run
either from the command line or from the FDT gui.
I recommend you use that.
All the best,
Mark
