Hi all,
I have a ascii file with several million lines which is defined as follows:
< startblock >
value value2 value3
.
.
.
< endblock >
< startblock >
value value2 value3
.
.
.
< endblock >
My goal is to go into each block and read the values inside. If these values are of interest I want to select the entire block and save it as a new file. Can someone give me some insight on how to do this?
Thanks in advance!
Best regards
Joao

Do you have enough memory to be able to read the entire file at one time and then analyze it?

If these values are of interest I want to select the entire block what's the criteria to select? I think what you have is a x,y,z data. At the end you want to plot and see?
