I'm trying to fit a line for a linear regression but I keep getting NaNs when using polyfit. I attached the data and the matlab files.

Hello TimaMarie,
yes, polyfit doesn't like NaNs. One way out is, just before doing polyfit, toss out the elements of both variables if either one of them is a NaN:
ind = isnan(con_WABA) | isnan(WAchl);
con_WABA(ind) = [];
WAchl(ind) = [];
