Spinworks and MatNMR Inconsistencies

I'm pretty new to NMR, and am just trying to do some simple data processing with a 1D ethanol spectrum I got from a Bruker spectrometer. I opened it in Spinworks and it appears to be normal, when I take the Fourier transform the spectrum is what I expected. I wanted to process this in Matlab however, so I used MatNMR to load the FID into Matlab. It seems though, that a lot of the data is for negative time values. When I take the Fourier transform it looks quite different and is considerably more noisy.

Given that the data is the same, is there something that spinworks does differently to the data, that I should correct for in Matlab?

Thanks :)
