==== usage ====
  * Copy wf2state to bin directory
  * run with *wf* file name as parameter, example:
    <code> wf2state 006_450.wf1 </code>
  * script generate ''006_450.wf1_state'' file

==== wf2state: ====
<code>
#! /bin/bash

input=$1
#input="006_450.wf1"

output=$input"_state"

n=`awk '(NR==3){print $1}' $input`
rc=`awk '(NR==4){print $1}' $input`
dx=`awk -v rc=$rc -v n=$n 'BEGIN{print (rc/n)}'`
lines=`cat $input | wc -l`

echo $lines $n $rc $dx

cat $input | tr D e > temp

awk -v lines=$lines -v dx=$dx 'BEGIN{x=0}
