Hi BrieAnna,

Consider using fgetl function to read the lines of txt. And also use strsplit to split the string and get the individual values you want.

strsplit returns a cell array, so remember to transform the cell element in string (letters) or double (numbers).

Ex:

fid = fopen('mytxt.txt');
line = fgetl(fid); % line = '0.000, 0.000, 0.000, 9.000'
line = strsplit(line,', '); % line = {'0.000'} {'0.000'} {'0.000'} {'9.000'}
freq = str2num(line{4}); % freq = 9.000
fclose(fid)
