Sorry for sending so many emails. The error for combine channel is due to sensortype.m cannot get my neuromag data type. I checked the length(grad.label). It's 612, double of 306 which is supposed. How can I settle it?
Thanks in advance.
Best,

Dear experts,
I checked the script of freqanalysis_wltconvol and founf the default for output was 'powandcsd'. This output needs combine channels. My meuromag data seems has problem on something related "combine channels".
It works when I change output as 'pow'. However, I wonder what might happen when using combining channels? I suppose it relates layout?
Thanks for suggestion.
Best,
Eve

Dear experts,
Could you give me ome suggestion for wavelet analysis? These parameters are OK in EEG data I count using ohter software. I don't think it's different for MEG data but the error happened...

??? Error using ==> zeros
Out of memory. Type HELP MEMORY for your options.
Error in ==> C:\MATLAB6p5\toolbox\fieldtrip-20070328\freqanalysis_wltconvol.m
On line 234 ==> if csdflg, crsspctrm = complex(zeros(numsgncmb,numfoi,numtoi)); end
Error in ==> C:\MATLAB6p5\toolbox\fieldtrip-20070328\freqanalysis.m
On line 170 ==> [freq] = feval(sprintf('freqanalysis_%s',lower(cfg.method)), cfg, data);
Any suggestions are appreciated.
Best,
Eve
