Importing Data from Neuralynx

[Natalia Grion]

Hi All,
I want to start with Fieldtrip analysis on animal data recorded with
Neuralynx. I have LFP (*.ncs files), spikes (*.nts), and event files
(*.nev). So, I have the three wrapper functions; which call these
read_xxx functions that detect the file format and subsequently call the
appropriate low-level function for each file format.
In a first attempt to import data I ran:
hdr = read_fcdc_header(file) with a *.ncs file
but I found this error:
??? Undefined command/function 'read_neuralynx_ncs'.
Error in ==> fieldtrip-20070820\private\read_header at 472
    ncs = read_neuralynx_ncs(filename, 1, 0);
Error in ==> read_fcdc_header at 37
[hdr] = read_header(varargin{:});

Do you have any explanation for this error?
Another question:  Are *.nst  (spike files) recognized?

Thank you all!!
