Re: Findpeaks function

Hi,

The first step is always to read the documentation clearly. This is
written in the help of the function

"DoubleSided"
          Tells the function that data takes positive and negative
          values.  The base-line for the peaks is taken as the mean
          value of the function.  This is equivalent as passing the
          absolute value of the data after removing the mean.

Also check the demos (none with negative data, but shows other aspects
of the function)
