[FieldTrip] (no subject)

[Schoffelen, J.M. (Jan Mathijs)]

Hi Peter,

https://code.google.com/p/fieldtrip/source/browse/trunk/ft_clusterplot.m

My change was dated the 11th (see the above link). I believe that you just had the bad luck to have an FT copy that had a bug in it. I suggest to upgrade to the 20150812 version (just to be sure).
Best,
Jan-Mathijs

Hi Jan-Mathijs,

I believe you may be correct. The error I had received was from a recent Fieldtrip download (20150810). I ran my script again on an older version (20150522) I have installed on another computer and the plot came out great.

Thanks again for your help!

Peter

Hi Peter,
I cannot reproduce your problem. Are you using the latest version of fieldtrip. I very recently fixed a bug in ft_clusterplot, which could well explain your problem. If you are actually using the most recent FT-version, then my change might have introduced a bug :o).

Best,
Jan-Mathijs
