style='font-size:10.0pt;font-family:Verdana'>Hi everyone,<br>
<br>
I would like to use the values that correspond to the interpolated statistics
at source level. <br>
The problem is that most of these values are NaNs, even tough I can visualize
them with sourceplot.<br>
<br>
Here are the steps I am doing to compute these values:<br>
<br>
[signal1] = sourcegrandaverage(cfg,data);<br>
[signal2] = sourcegrandaverage(cfg,data);<br>
<br>
[Stats] = sourcestatistics(cfg,signal1,signal2);%the statistics used here is
depsamplesT using fdr and clusterstatistics = maxsum<br>
[SourceInterpolatedSats] = sourceinterpolate(cfg,Stats,template_mri);<br>
<br>
This yields:<br>
<br>
SourceInterpolatedSats =<br>
<br>
inside: [91x109x91 logical]<br>
stat: [91x109x91 double]<br>
dim: [91 109 91]<br>
transform: [4x4 double]<br>
anatomy: [91x109x91 double]<br>
cfg: [1x1 struct]<br>
<br>
But when I try :<br>
<br>
SourceInterpolatedStats.stat([20 45 68]) = <st1:place w:st="on">NaN</st1:place>.<br>
And this holds true for almost any index.<br>
<br>
Does anyone know if it's possible to access these values?<br>
<br>
