Re: NaN number in ASCII file

[Jörg Kaduk <joerg@xxxxxxxxxxxxxxxxxxx>]

Hi Xavier,
I also have to deal with this problem and, as Mark and Glenn
suggested, I use sed to get rid of the NaN and put -1.e+34
in - which is ferret's standard for missing values.

I use a little shell script which works itself through
a couple of directories and files - in this case
through all files of all subdirectories of the the
directory '1998':

#!/bin/sh
for f in `ls 1998/*/*`
do
  sed -f xx $f > yy
  mv yy $f.new
done
 
In the file xx there is just the edit command for sed:
cecropia.Stanford.EDU(214): more xx
1,$s/NaN/-1.e+34/g
 

Good luck,
Joerg
