Dear Fieldtrip mailing list members,<br>
<br>
I am a quite new user of fieldtrip (version 10090331). <br>
I have been trying to use it for analyzing distribution of frequencies
on MEG signal between two events of a task.<br>
The last command using freqstatistics result of an error message.<br>
I decided to run the tutorial "Cluster-based permutation tests on
time-frequency data" in order to compare the organization my data set
compared with the one in the data set. In fact I got the same bug with
the tutorial data set that is for the tutorial data set:<br>
<br>
selected 149 channels<br>
selected 61 time bins<br>
selected 1 frequency bins<br>
Warning: PACK can only be used from the MATLAB command line.<br>

In fieldtrip-20090331/private/statistics_wrapper at 315<br>
In freqstatistics at 137<br>
Using the gradiometer configuration from the dataset.<br>
there are on average 4.7 neighbours per channel<br>
using "statistics_montecarlo" for the statistical testing<br>
using "statfun_indepsamplesT" for the single-sample statistics<br>
constructing randomized design<br>
total number of measurements = 149<br>
total number of variables = 1<br>
number of independent variables = 1<br>
number of unit variables = 0<br>
number of within-cell variables = 0<br>
number of control variables = 0<br>
using a permutation resampling approach<br>
computing a parmetric threshold for clustering<br>
Warning: Not all replications are used for the computation of the<br>
statistic.<br>

Undefined function or method 'tinv' for input arguments of type
'double'.<br>
??? Error using ==> statistics_montecarlo at 278<br>
could not determine the parametric critical value for clustering<br>
<br>
Error in ==> statistics_wrapper at 381<br>
[stat, cfg] = statmethod(cfg, dat, cfg.design);<br>
<br>
Error in ==> freqstatistics at 137<br>
[stat] = statistics_wrapper(cfg, varargin{:});<br>
<br>
>> <br>
<br>
Any idea or suggestion about that problem?<br>
<br>
Thanks.<br>
