dear jcohenadad, thank you for your reply.
I think I have understood the sct.
1.I have the question. I have only one t1 imaging of c1-c7. however ,I have 3 t2 imaging (c1-c3,c3-c5,c5-c7),and 3 dti imaging (c1-c3,c3-c5,c5-c7). if I could put t1(c1-c7) in t1 folder, and t2(c1-c3) in t2 folder, dti(c1-c3) folder to calculate the dti (c1-c3) data ?
2. I think I have no the imaging of t2s ,what should I do? these are all imaging I have.
thank you .
