Reading 4D data

[Laura Parkes]

We are trying to read in 4D neuroimaging data using the FCDC_read_data 
command and the 4D toolbox from Christian Weinbruch. We are having a few 
problems...
We get this when we attempt to run:
________________________________________________

read_fcdc_data('con1')
Warning: cannot determine whether the 4D-VERSION toolbox is present
Warning: adding 4D-VERSION toolbox to your Matlab path
Warning: Name is nonexistent or not a directory: 4d-version.
con1.m4d
File Format is FLOAT
TotalChannels = 162
 = 13598
SamplePeriod is 0.001475
FirstLatency is -0.050000
Duration is 20.051067
LastSample is 20.001067
reading coil locations
I found a MSI.Meg_Position_Information.Begin:
??? Cell contents indices must be greater than 0.

Error in ==> fieldtrip-20061011\private\read_header at 173
      hdr.label{indx} = sprintf('EEG%03d', i);

Error in ==> fieldtrip-20061011\private\read_data at 157
  hdr = read_header(filename, 'headerformat', headerformat);

Error in ==> read_fcdc_data at 49
[dat] = read_data(varargin{:});
_______________________________________________________________

The warnings are odd as the 4D toolbox directory is set in the matlab path 
and we have copied the files into fieldtrip/private.

The later error message is also odd as when we run 'read4D' on its own we 
don't get this error. 

We would be grateful for any help or suggestions.
