<div dir="ltr"><div><div> Hi! Low SNR in multi-shell data with high b-values are a
problem for all the higher order models, including MAP-MRI and many
compartmental models. <br></div><div>Moreover, MAPMRI presents numerous parameters tha you can adjust in order to maximize its performances. Can you give us more information on your dataset? E.g. SNR, number of samples, number of b-values, etc.<br><br></div>Kind regards,<br><br></div>Mauro <br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 3, 2018 at 8:43 PM, Ping-Hong Yeh <span dir="ltr"><<a href="mailto:pinghongyeh@gmail.com" target="_blank">pinghongyeh@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Dipy users, <div><br></div><div> I am wondering if the <span style="color:rgb(0,0,0);font-family:"Lucida Grande","Lucida Sans Unicode",Geneva,Verdana,sans-serif;font-size:14px;letter-spacing:-0.14px">MAP-MRI</span><span style="color:rgb(0,0,0);font-family:"Lucida Grande","Lucida Sans Unicode",Geneva,Verdana,sans-serif;font-size:14px;letter-spacing:-0.14px"> </span>measures such as RTOP, RTAP, RTPP, NG etc are ready to use for between-subject comparisons.
