I have a data file with 10 columns and 28380 rows. I want to manipulate only the 7th column and reassign the values to the data. How do I do it ??

What kind of data file is it? .xlsx, .csv, etc.?

If it is an ASCII data file, then read the file, do the computation(s) on the column in question and rewrite it.

If it were an Excel file you could use xlsread|xlswrite to read the specific column but there's not a general way to write a portion of a text file.
