lyman: v0.0.5 (November 7, 2014)

Preprocessing workflow

• Added a workaround some changes in later versions of FSL that now return a de-meaned timeseries from the highpass filter. In FEAT, the mean is replaced, and the rest of the processing carries on as usual. Because I don't want to break compatability with older versions of FSL, this adds back in the mean but only if it looks like the filtered timeseries has been de-meaned. Note: This uses a simple heuristic, which may not be robust in all cases, so it is important to check that the signal-to-noise maps make sense if you are doing something that expects a nonzero timeseries mean.
