[FieldTrip] correct use of ft_read_data

Dear Fieldtrippers,

could you help me make ft_read_data work?

the data is a <34x48128 double>.

the header looks like this:

h =
          nChans: 34
        nSamples: 48128
     nSamplesPre: 0
         nTrials: 1
              Fs: 512
           label: {34x1 cell}
            orig: [1x1 struct]
        chantype: {34x1 cell}
        chanunit: {34x1 cell}

I want to read one channel to define the trials in my trialfunction.

  t=ft_read_data(cfg.dataset,'header',h,'chanindx',17)

Attempted to access dat(17,:); index out of bounds
because size(dat)=[1,48128].

Error in ft_read_data (line 294)
       dat(i,:) = dat(i,:).*
       parameters.SourceChGain.NumericValue(i) +
       parameters.SourceChOffset.NumericValue(i);

Best
Steph
