[Eeglablist] importing ascii data with unusual organization

Hi -

I'm trying to import data into EEGLAB from an ascii file format and am 
having a problem getting the data formatted
correctly. The raw data is epoched into individual trials before 
conversion to ascii format, and each trial is separated by
a mini-header file that includes electrode (numerical) and trial 
information including behavioral data. We sample at 200 Hz
and each trial contains 400 data points. A sample trial from the ascii 
file is as
follows at electrode '0' :

     0     1     4     4  1486
  1897  1910  1921  1914  1907  1923  1924  1936  1923  1906
  1908  1911  1921  1927  1894  1898  1903  1914  1912  1900
  1902  1904  1899  1912  1914  1917  1914  1916  1928  1919

  2124  2108  2119  2117  2135  2137  2179  2221  2229  2260

Each electrode is separated by the header in line 1. Is there any way to 
successfully import data as formatted above without substantial 
re-organization?

Thanks a lot!
