<br></div><div style="font-family:arial,sans-serif;font-size:14px"> I am a mrtrix user. I have touched you for several times. Recently I am reverting the process of calculate the CSD. I have simulated a DW data using DTI method. For example, b0=3000, S0=323, diffusion tensor is [0.000021 0 0;0 0.000034 0;0 0 0.00069], so we can simulate the diffusion signal of each b-vector.</div>
<div style="font-family:arial,sans-serif;font-size:14px"> When I calcultate the response function using this data, I found the result of a voxel is as below: (1)the result of mrtrix: 632.706 -295.359 71.4767; (2)the result that I use matlab to solve equations is: 1.105 -1.153 0.1241.<br>
</div><div style="font-family:arial,sans-serif;font-size:14px"> So I really want to know the error resson of my idea. If you want more detail, we can get more contact. Thank you very much.</div><div style="font-family:arial,sans-serif;font-size:14px">
