Hello,
First, as we open the dti-data, some of the gradient directions that we have (30) are not seen completely (most of them are working). The placement of the missing data varies between the gradient directions. What could be the problem?
Second, we wish to obtain DTI-maps by using FDT, however our bvecs and bvals are not accepted. Perhaps something wrong with the text editing? The data is presented here below, where we have 5b0 and 30dir.
