I have a similar problem with a string/replacement
132435 321350 35465162 6561516
546516 654613 65462133 6584652
and so on for some hundreds (!!) raws.
What is the best way to edit this textfile to have something like this?
Basically, I have to change the 'double space' in comma and put a minus in front of the second and forth block of numbers every raw.
Thanks a lot for any help or suggestion
