<div dir="ltr">Thank you very much Robert. I tried your suggestion, and set the cfg.parameter='stat', still it gets stuck. As you mentioned, it maybe out of memory. I am now trying to change to a powerful one.<br><br>

<br>
I suspect that your computer is running out of memory while it is trying to interpolate all functional volumes onto the anatomical MRI grid. Instead of specifying<br>
<br>
cfg.parameter = 'all'<br>
<br>
I suggest that you only specify those parameters that you want to have interpolated. The negclusterslabelmat volume for example is not one that you want to have interpolated.<br>

Dear all,<br>
<br>
I am now working on the sourcestatistics of the LCMV beamfomer. After finished the volumenormalisation, sourcegrandaverage and sourcestatistics, now I want to plot the t-values to the anatomical MRI. However, when I run the ft_sourceinterpolate (codes see below), I wait for hours and response with the matlab informing that "reslicing and interpolating negclusterslabelmat "<br>
--------------------------------------<br>
%%statistics on the grandaverage<br>
cfg=[];<br>
cfg.dim = gs42.dim;<br>
cfg.parameter = 'nai';<br>
cfg.method = 'montecarlo';<br>
cfg.statistic = 'depsamplesT';<br>
cfg.correctm = 'cluster';<br>
cfg.numrandomization = 100;<br>
cfg.alpha = 0.05;<br>
cfg.tail = 0;<br>
<br>
nsubj=length(gs42.trial);<br>
cfg.design(1,:) = [ones(1,nsubj) ones(1,nsubj)*2];<br>
cfg.design(2,:) = [1:nsubj 1:nsubj];<br>
<br>
cfg.ivar = 1; % row of design matrix that contains independent variable (the conditrions)<br>
cfg.uvar = 2; % row of design matrix that contains subjects number-2 groups<br>
<br>
stat = sourcestatistics(cfg, gs42,gs50);<br>
<br>
sMRI = read_mri(fullfile(spm('dir'), 'canonical', 'single_subj_T1.nii'));<br>
cfg = [];<br>
cfg.downsample = 2;<br>
cfg.parameter = 'all';<br>
statplot = ft_sourceinterpolate(cfg, stat, sMRI);<br>
--------------------------------------------------------------------------------------<br>
<br>
Does anybody how to deal with it? Thanks a lot in advance.<br>
<br>
Best,<br>
