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

Dear all,<br>
I am having problems running the tracks2prob command. I am running it as follows:<br>
<br>
"tracks2prob cst_dt.tck anat.mif tract.mif"<br>
<br>
and I get the following error:<br>
<br>
"expected exactly 2 arguments (3 supplied)"<br>
<br>
if I use the -version option I get<br>
<br>
"Mrtrix 0.2.9, glib 2.26.1, GSL 1.14, (build Mar 14 2011)"<br>
<br>
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.<br>
<br>
Could this be a problem with the latest build of MRtrix? Any help would be greatly appreciated<br>
<br>
