Good afternoon,
I am trying to read a txt file that has
  • 11 lines of header
  • 8000 values
  • 2 lines of string
  • 8000 values
  • 2 lines of string
  • 2 lines of string
  • 8000 values
  • ....
I know how I can skip the header but not how to skip those 2 string lines every 8000 values.
Thank you a lot
Anna

Hi Anna,
I understand that the 8000 values contains the values as numeric types.
You can read all the values as strings from the text file, and ignore those values which are non-numeric. This can be checked by using the str2double function.
