Hi,
I’m just starting to learn Mathematica and have the need to plot large data files, how can I select only specific data from the file. The documentation I’ve seen explains how to read only the first N samples but I have not seen a way to grab data from the middle of the file.
All help appreciated,
Ed
The easiest way to work with a data file is to Import the entire thing and then work with it. Is the file too big for that?
If you want to select the middle section of a table of data, you can use Part with “;;” syntax.
myData[[All, 50;;100]]
That selects All Columns and the 50th thru 100th rows of the dataset called myData.
