[FieldTrip] plotting tutorial

[Wong-Barnum, Mona]

Hi:

	I’m working my way through the plotting tutorial at http://www.fieldtriptoolbox.org/tutorial/plotting/.  I would like to use the neuromag306all.lay layout to plot the data.  I tried the neuromag306.mat from ftp but that didn’t work; it seems the data read in from neuromag306.mat doesn’t actually contain any data:

>> sens

sens = 

  struct with fields:

    chanpos: [2x3 double]
    elecpos: [2x3 double]
      label: {2x1 cell}
       unit: ‘cm'


	I have my own neuromag .fif file but not sure how to use the layout to plot my data (read in following the instructions at page http://www.fieldtriptoolbox.org/getting_started/neuromag/):

>> hdr

hdr = 

  struct with fields:

          label: {389x1 cell}
         nChans: 389
             Fs: 603.1072
           grad: [1x1 struct]
           elec: [1x1 struct]
       nSamples: 192000
    nSamplesPre: 0
        nTrials: 1
           orig: [1x1 struct]
       chantype: {389x1 cell}
       chanunit: {389x1 cell}


	All tips/help are appreciated.

thanks,
Mona
