Hi, I'm trying to use eddy tool to correct my DW data. When I run the tool i receive these message: I'm thrown terminate called after throwing an instance of 'EDDY::KMatrixException' what(): KMatrixException: msg=MultiShellKMatrix::SetDiffusionPar: Data not shelled Aborted In my experiment I'm using one b_0 and 11 b-values from 200 to 5000 s/mm^2. For each b-value I have 15 directions. I have already used eddy on the same data but dividing the 166 4D-volume in three separate 4D-volumes and it worked. Thank you in advance. Michele.
