Hi All,
Ive been trying to load data from the .txt file that I've attached. What I've got so far is:
Spill = importdata('Spill.txt');
T = Spill(:,1);
C = Spill(:,2);
but I get an error "Index exceeds Matrix Dimensions". Can some please help me out. I can't change to ".data" file either as I have to extract the columns of data directly out of the .txt file. Much appreciated in advance.

To read a tab delimited ascii file while skipping the first row, try:
data = dlmread('Spill.txt','\t',1,0);

It depends on that MATLAB release you are using. Text anywhere in a file is not supported in R2014b or earlier, and possibly not in R2015a either (we have not gone back to figure out exactly when the change was made.)

fid = fopen('Spill.txt', 'rt');
data = cell2mat( textscan(fid, '%f%f', 'Delimiter', '\t', 'HeaderLines', 1) );
fclose(fid)

I think it is much easier to use textread function. Following link describe in full detail how to use this function to import data from a text file:
