Re: [Chris Charley] Extract from text file, basic trig functions, then graph

Hi Chris,

Many thanks for the reply. I should have checked the sample file properly before I posted (was just trying to keep it small), and can see it only had one set of data... this format actually repeats over and over again, and the filesize is realistically ~1.5 Gb in total!

I was intending to extract each of the matched records to a unique file (of the same ID) in an attempt to keep the file sizes down when moving on to the math, and then graphing etc.

So for my new sample attached (using my original code - which should have had \n), I would get the below for ID 1:


Code
453448.0,7998331.8 
453454.4,7998327.5
453461.6,7998322.9


Hope that makes sense?
