Reorienting dwi data and bvecs

2

Dear @LauraNeuro,

There is a simple method to output the correct gradient directions:

  1. run dwigradcheck on your original data and export the corrected diffusion table -
for_each */ : dwigradcheck IN/dwi/dwi.mif -export_grad_mrtrix IN/dwi/fixed_bvecs.txt
  1. run mrconvert using the fixed gradient table -
for_each */ : mrconvert IN/dwi/dwi.mif IN/dwi/dwi_fixed.mif -grad IN/dwi/fixed_bvecs.txt

Hope this helps,

Nick
