275 CTF Channel datasets

[Robert Oostenveld]

Hi Matthias,

Welcome in our community ;-)   I know that Tom Holroyd of the NIH and 
some of his colleagues) are working with FieldTrip on 275 channel CTF 
datasets, and I have also tested the code myself with 275ch CTF data. 
So I guess it should work...

You could try
   hdr = read_fcdc_header('thenameoftheres4file');
   dat = read_fcdc_data('thenameofthemeg4file', 1, 600);
If that does not work, there is a real bug in FieldTrip.

If you cannot get it to work, could you send me a zip file with your 
dataset, *EXCLUDING* the meg4 file. Then I can check whether the header 
information is read in correctly. That is the part of the dataset that 
might be binary incompatible, the binary format of the meg4 file is so 
simple that I cannot imagine that it is different for your new system.

best regards,
Robert

PS pls don't send the zipfile to the discussion list, but to me directly
