hi,
assuming that your 3D nii do not contain the info, there isn't any way to achieve what you want. you need to go back to your dicoms and/or know what the scanner did recording the data.
sorry.
cheers-
andreas

Betreff: [FSL] 3d nii to 4d with bvec and bval
Dear FSL experts,
I have been previously using mricron for conversion of dicom images to nii format with bvec and bvalue to be used in TBSS. The current problem is that I have received 3d nii format of DWIs. There is "fslmerge" to convert 3d to 4d files, but with this command I won't receive bvec and bval files. Mricron also comes short when the input is a 3d nii. Could you please give me a clue of how to convert 3d nii to 4d files with bvec and bval?
Any suggestion is gratefully appreciated.
Regards,
Arman
