Hi Venkat,<div><br></div><div>I don't think there is anything like that in DTIstudio, you may need to do some manual work. For fiber statistics you should first create the fibers and then hit the button Statistics, then copy the value you want to an excel file... for each subject. The FA values for a fiber trackt could be calculated in Matlab, once you export the FA map and the fiber map as analyze format. Then its just a matter of loading both files in Matlab and using the fiberw as a mask for the FA map (multiplicate them) and obtain the mean.</div>
<div><br></div><div>Hope this helps.</div><div>Dorian<br><br><div class="gmail_quote">2013/1/24 Venkatesh Rajagopalan <span dir="ltr"><<a href="mailto:VRajagopalan@kesslerfoundation.org" target="_blank">VRajagopalan@kesslerfoundation.org</a>></span><br>

<p class="MsoNormal">Dear MRIstudio Users,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We are interested in studying structural connectivity in ALS patients. We are working on network analysis where we would like to measure for instance mean FA in fibers running between two ROIs. We have 165 such ROIs and we would like to
measure the number of fibers, mean FA between each of the ROI with each other. I am wondering whether DTI studio or MRI studio or ROI editor has these options to do automatically in a given subject.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks<u></u><u></u></p>
