Is there a way to use load to load a text file but skip a few lines which contain headers and other info and just load numerical data in columns that come after the headers?

Hi Baba, try importdata:
importdata(FILENAME, DELIM, NHEADERLINES) loads data from ASCII file FILENAME, reading numeric data starting from line NHEADERLINES+1.

Using importdata with nheaderlines specified works for almost every file for me, but for some reason, I have one file that instead of skipping the first 20 lines as I want, instead imports ONLY the first 20 lines. I have no idea what would cause this to happen, does any one know of any circumstance in which this would happen? The file is a .txt file and has nearly 85k lines of data. The command I used is d = importdata('data.txt',' ',20);

Shania Hurst, I suggest you consider using readtable() with HeaderLines . (readtable() might even be able to figure out for itself how many header lines are there.)
