[Mrtrix-discussion] 2 NEX

[romain valabregue]

Dear All

I have an acquisition which has been done with the same direction twice. 
(this was an error intead of using a complementary set of direction it 
uses the same diffusion directions)

when I do the estimate_response on the all data set I get wrong estimation

  cat response.txt
-4.04413e+15 1.47696e+14 -1.52359e+15 -3.50894e+15 6.85026e+15


but when I do the estimation on the half of the dataset (either the 
first one or the second one)
I get a correct estimation

cat response_sh.txt
504.145 -226.698 65.6188 -14.786
cat response_sh2.txt
492.199 -215.285 64.4914 -10.5965


Any idea how I can handle the 2 NEX correctly in mrtrix


Thanks


Romain
