Thanks for your quick reply. I scanned the tutorials and I could not
find one that is using clusterrandanalysis.m. I only found a matlab
"Apply clusterrandanalysis on TFRs of power that were computed with
but as it is only a script I cannot access the data.
So far I was capable to run freqanalysis.m by adapting my data to the
format described in the documentation. However, when I run
clusterranalaysis.m with the output of freqanalysis.m being 'freq'
[clusrand] = clusterrandanalysis(cfg2,freq,freq); % I am using twice
'freq' as a test run with cfg2.statistic: 'indepsamplesZcoh'
, I keep on getting errors such as :
??? Reference to non-existent field 'dof'.
Error in ==> fieldtrip-lite-20070920/private/clusterrandstatistics at
And if I had the option:
cfg.calcdof = 'yes'
to get the degree of freedom, I get this other error:
??? Undefined function or variable "cumtapcnt".
Error in ==> freqanalysis_mtmfft at 389
if calcdof && ~exist(cumtapcnt)
Could you please tell if I am using a wrong configuration variable or
if there is a problem in the code?
