problem on wavelet analysis, combine channel

[alotof eve]

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
