<p>Dear fieldtrip users, <br>
</p>
<p><br>
</p>
<p>I've downloaded and added to my path on Matlab the MVPA-Light-master toolbox. I'm using MATLAB R2014a. After preprocessing and segmenting my data I tried to run the classification accuracy following the steps in the fieldtrip MVPA Light tutorial: <a href="http://www.fieldtriptoolbox.org/tutorial/mvpa_light/">http://www.fieldtriptoolbox.org/tutorial/mvpa_light/</a><br>
</p>
<p><br>
</p>
<p>This is the code I have for the classification during the latency chosen: <br>
</p>
<div><br>
</div>
<div>%Classification in 0.5 0.7 latency</div>
<div>nFaces = numel(face_timelock.trial);</div>
<div>nVase = numel(vase_timelock.trial);</div>
<div><br>
</div>
<div>%%Define the configuration struct</div>
<div>cfg = [];</div>
<div>cfg.keeptrials = 'yes';</div>
<div>cfg.method = 'mvpa';</div>
<div>cfg.layout = 'biosemi64.lay';</div>
<div>cfg.mvpa.classifier = 'multiclass_lda';</div>
<div>cfg.mvpa.metric = 'accuracy';</div>
<div>cfg.mvpa.k = 5;</div>
<div>cfg.latency = [0.5, 0.7];</div>
<div>cfg.avgovertime = 'yes';</div>
<div>cfg.design = [ones(nFaces,1); 2*ones(nVase,1)];</div>
<div><br>
</div>
<div>stat = ft_timelockstatistics(cfg, face_timelock, vase_timelock);<br>
</div>
<div><br>
</div>
<div>When I run this bit, I keep getting this error message: <br>
</div>
<div>Error using ft_timelockstatistics (line 162)<br>
</div>
<div>could not find the corresponding function for cfg.method="mvpa"<br>
</div>
<div><br>
</div>
<div>When I look into the script for ft_timelockstatistics, this is what I find in the lines that specify what stats can be used with the cfg.method function:<br>
</div>
<div>
<div>% fetch function handle to the intermediate-level statistics function</div>
<div>statmethod = ft_getuserfun(cfg.method, 'statistics');</div>
<div>if isempty(statmethod)</div>
<div> ft_error('could not find the corresponding function for cfg.method="%s"\n', cfg.method);</div>
<div>else</div>
<div> fprintf('using "%s" for the statistical testing\n', func2str(statmethod));</div>
<div>end<br>
</div>
<div><br>
</div>
<div>I am not sure what I am doing wrong. Any help/input would be very much appreciated. <br>
</div>
<div><br>
</div>
<div>Thank you! <br>
</div>
<div><br>
</div>
<div>All the best,<br>
