Dear dr. Maris,

Allow me to ask you one more question about the cluster-based analysis.
I have three groups but I'm only interested in two combinations:
group A versus B and 
group B versus C

Is it allowed to do two single cluster-based analyses with the above 
mentioned pairs and with a Bonferroni correction of the p-value for the two 
comparisons or is it required to run a single three-group analysis using the 
indepsamplesF statistic?

I know I already asked you this question earlier but a bit different, but I'm still 
insecure about this. You answered my previous question with:
alternatively, you may run a single three-group analyis...
But are two single cluster-based analyses also allowed in this case in your 
opinion?

Many thanks in advance,
Best emanuel
