clusterrandanalysis input format

[Rodrigo F. Salazar]

Hi Eric,

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
script named:

"Apply clusterrandanalysis on TFRs of power that were computed with
BESA"

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
680
             dofc1=reshape(sum(data.dof(replselc1,:,:),1),
1,nfreq,ntime);

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?

Thanks,

Rodrigo.
