header files

[Brad Robbins (BIO)]

I have a small data set that I want to manipulate in GRASS.  The problem 
is the header file.  Creation of this file requires that I specify the 
number of rows, columns, and bytes per cell.  As you know the product of 
these 3 values must equal the file size.  My file is 125124 mb.  I have 
400 columns and 107 rows.  Dividing the file's size by the product of 
columns and rows indicates I have 2.9 bytes per cell.  This isn't 
acceptable of course.  I believe my problem lies in the presentation of 
the data.  I used a spreadsheet (Microsoft's Excel) to enter the data and 
saved it as a text file.  This program is limited to 256 columns so I 
wrapped the columns down to the next line, starting a new line at each 
new row.  Is this my problem?  If so does anyone have a suggestion as to 
how I might create a text file without this problem?  Your help is 
appreciated.
