[Mrtrix-discussion] tracks2prob error "expected exactly 2 arguments......"

[Ashmore, Jonathan]

Hi all,
thanks for all your help. Including the template option did the trick.
Thanks again

Hi Jonathan,
I have a later version of track2prob but I think the problem is that you are missing the "-template" option.
Try this to see if it works:
"tracks2prob cst_dt.tck -template anat.mif tract.mif"
i.e. you need to let tracks2prob know that "anat.mif" is the template, and therefore "tract.mif" will be the output.
I hope this solves the problem.
Cheers,
Fernando

Dear all,
I am having problems running the tracks2prob command. I am running it as follows:

"tracks2prob cst_dt.tck anat.mif tract.mif"

and I get the following error:

"expected exactly 2 arguments (3 supplied)"

if I use the -version option I get

"Mrtrix 0.2.9, glib 2.26.1, GSL 1.14, (build Mar 14 2011)"

When I run exactly the same command with exactly the same files on an old version of mrtrix (I am not entirely sure how old since I don't have access to the system currently - but potentially over a year old) I do not get these errors and the tracks2prob command works fine.

Could this be a problem with the latest build of MRtrix? Any help would be greatly appreciated

Jonathan
