I am having a trouble using importdata

I need to import the numerical data from this text file: http://sdrv.ms/1cbm8uU

I have found success using importdata for all the text files I have used except for this one.

This is the code that I am using:

data_file_modtran = '10410 EDZE Essen Observations.chn'; 
d=importdata(data_file_modtran,' ',5); 
data_bands_modtran=d.data; 
data_bands_modtran=data_bands_modtran(1:16,:);

The only column of data being imported is the last column. I really only need the 4th column.

Why isn't my code working?

Do any of your other files have the second set of headers in the middle of the file?

Yes, most of them do. If I need the data from the lower half, I just find out the size of the upper half, and I use import data again, but this time I have it start at (length+4). In this case, I don't need the data below because it is just a duplicate of the top.
