Hi all, I have a large text file, about 7000 lines, and I need to read and edit specific lines, 300 lines, in the middle of the file. How can I skip unneeded lines?

Some more details?
Do you know which specific line number, line content you should start editing?

If you already know the line number that you need to edit, I suggest to use one of the following solutions on matlabcentral https://de.mathworks.com/matlabcentral/answers/62986-how-to-change-a-specific-line-in-a-text-file
If you dont know your line number yet, but know some test-marker (f.ex. TEMP....TEMP) you can read on the Matlab functions
