For performing tractography, I wish to execute dwi2mask, dwi2response, dwi2fod one after another. But unfortunately I am stuck at dwi2response. I am trying to execute it with tournier, according to the document on this link.
I do not get any error stating that the no. of arguements is less than necessity, but I get error regarding mrconvert function, which I am supposing would be performed eventually for the dwi2response.
Please find the code and the error shown below.

Please help me rectify this issue.
