Hi, The file has "...." for missing data. The commands for reading
text data do not automatically handle missing data. Ferret reads
all of the data for each column and analyzes the text. If a
column has any text which can't be interpreted as numeric values,
it is marked as being of type string. I would suggest you edit
the file and replace "...." with a fixed numerical value, perhaps
a large negative value such as -99999. Then after opening the
file with the columns command, assign that value as the
missing-value flag, for the numeric columns: yes? columns/delimiter=" " edited_file.txtand likewise set the flag for v5 through v9. You can also give the variables meaningful names, units and titles with more qualifiers on the SET VARIABLE/ command. Ansley On 11/16/2017 3:05 AM, Gopal Mondal
