Reading continuous data files - chanindx error

[Eric Jackson]

I am trying to run "preprocessing" with a continuous data set from a 275-
channel CTF machine, but I get an error in the function read_ctf_meg4 
saying, "No channels were specified fr reading CTF data." The channel 
specification used in the cfg file is "cfg.channel = {'MEG' 'STIM']".  
Examining the function, it looks like nothing is being passed 
to "chanindx".

Is the problem with my channel specification or elsewhere?

Any assistance would be appeciated.  Thank you.
