Hello Doug

The Siemen's Trio gives us Diffusion weighted images in the form of MR.10284.746.

There are no extensions such as .dcm or .ima

I can convert the dicom to nifti .nii format using SPM or FSL.

But neither program extracts the bval or bvec information.

I am working on Mac OsX 10.5 and am using FS v4.3.1

I tried using 

mri_convert subject/MR* dwi.nii -it siemens_dicom

I am trying to ckeck the quality of the DWI and hence would like to perform eddy current correction and preprocess the images to generate FA maps.

Thanks in advance
