Hi Matthew,
<div class=""><br class="">
</div>
<div class="">The error tells you that it is impossible to determine a parametric critical value for clustering.</div>
<div class=""><br class="">
</div>
<div class="">You should either:</div>
<div class=""><br class="">
</div>
<div class="">-specify a cfg.statistic that points to an ft_statfun_something that internally contains some code that does the computation of the critical value. This typically pertains to a statistic for which known parametric distributions exist, e.g. a T-statistic,
or an F-statistic.</div>
<div class=""><br class="">
</div>
<div class="">-explicitly set a cfg.clustercritval to be an upper and lower numeric threshold for clustering.</div>
<div class=""><br class="">
</div>
<div class="">-use a different specification of cfg.clusterthreshold, e.g. ’nonparametric_common’.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>

I have had a script for my statistics that uses ft_statistics_montecarlo for the method in ft_freqstatistics. I downloaded the latest version of FieldTrip recently and now my scripts do not work. I get the following errors:</div>

I'm not sure what could be driving this issue, especially since I have made no changes to the script. The only thing that changed was downloading the lastest version of Fieldtrip. Is anyone else experiencing this? Or does anyone have advice into how it works?</div>

I've looked up the error message and one user recommended testing that running with cfg.method = 'analytic' works. I've done this and my script runs fine. The structure it outputs gives me appropriate values (no NaNs).</div>
