I've tried to use this function:
[ID,Domes,Location,lat,long,height] = textread('slr_sites.dat','%d%d%s%s%s%s','headerlines',2,'whitespace',' \b\t\n\r');
I keep getting the error: ??? Error using ==> dataread Trouble reading integer from file (row 2, field 2) ==> .4784603e+002\n
Can anyone fix this?

Your second column cannot be stored as integers. There's a letter "S" or "M" in it. This should work (note the format string):
[ID,Domes,Location,lat,long,height] = textread('slr_sites.dat', '%d%s%s%s%s%s', 'headerlines', 2, 'whitespace', ' \b\t\n\r');

How would I convert those strings into numbers after? Is there a scientific type conversion?

I was talking about the lat/long/h values. I would want to change them to the numbers with the exponent added on. Sorry about not being clear.

Why not use %f for those three fields?
