[Freesurfer] how to extract DTI data with bvals/bvects

Dear All,

I used unpacksdcmdir to unpack DTI data from Bay 3. The log file shows "DTI is in non-moasic form, so cannot extract bvals/bvects" My question is how to get bvals/bvects files from unpack?

The files look like:

42 DIFFUSION_HighRes ok 128 128 62 1 MR.1.3.12.2.1107.5.2.32.35162.2013031117224812856938134 43 DIFFUSION_HighRes ok 128 128 62 1 MR.1.3.12.2.1107.5.2.32.35162.2013031117224812950738135 44 DIFFUSION_HighRes ok 128 128 62 1 MR.1.3.12.2.1107.5.2.32.35162.2013031117224813055538136 45 DIFFUSION_HighRes ok 128 128 62 1 MR.1.3.12.2.1107.5.2.32.35162.2013031117224813122838137 46 DIFFUSION_HighRes ok 128 128 62 1 MR.1.3.12.2.1107.5.2.32.35162.2013031117224813209438138 47 DIFFUSION_HighRes ok 128 128 1 62 MR.1.3.12.2.1107.5.2.32.35162.2013031117224813279838139
