Hi,
I have never used fieldtrip before but I was trying to get familiar with its statistical analysis tools.
I tried to run the online example from:
http://www.fieldtriptoolbox.org/example/use_simulated_erps_to_explore_cluster_statistics
I am using MATLAB Version: 9.4.0.813654 (R2018a) and I downloaded that latest version of fieldtrip on 5 nov 2018
I face two errors:
first at ft_math function:
Error using ft_math (line 151)
the requested parameter is not present in the data
Error in Nonparametric_statistical_testingEEGandMEG_data (line 45)
difference = ft_math(cfg, timelock1, timelock2); % line 137 of ft_datatype_timelock removes the fields
and if I comment that line out, I face another error at ft_timelcokstatistics
Error using chol
Matrix must be square.
Error in montecarlo (line 13)
R = chol(Sigma); % Y = R^{-T}X has covariance I
Error in ft_timelockstatistics (line 185)
[stat] = statmethod(cfg, dat, design);
Error in Nonparametric_statistical_testingEEGandMEG_data (line 63)
stat = ft_timelockstatistics(cfg, timelock1, timelock2);
Any comment?
