v3.0.8

[2017/10/24: v3.0.8]
Faster manual GUI loading speed. Optimized caching
Improved drift resistance. Three average unit waveforms are computed based on the vertical spike positions,
and waveform similarities are compared for spatial and temporal shifts.
Faster post-hoc automated merging by using parfor (parallel computing toolbox)
Bugfix: manual GUI waveform similiarity matrix calculation.
Bugfix: Removed a horizontal curve from the rho-delta plot.
Bugfix: Manual GUI will clear the unsaved results when user selects "do not save".
Previously cached information was incorrectly shown when the manual GUI was restarted.
New default: Raw spike waveform duration is now the same as the filtered spike waveform length.
spkLim_ms = [-.25, .75]; sets the spike waveform range to 0.25 ms before the negative peak and 0.75 ms after the peak.
Setting spkLim_raw_ms = []; will set spkLim_raw_ms = spkLim_ms.

[2017/10/9]
Default changed: nPcPerChan=1 (previously 3), since other PC dimensions explain less than
2% of the total variance when differentiator filter is used. Using only the first PC is
also more robust to the presence of overlapping spikes.
New default filter: vcFilter = 'ndiff' (convolves with [1,2,-2,-1] if nDiff_filt=2 chosen).
The new differentiator filter is less attenuating than 'sgdiff' for small spikes,
which convolves with [2,1,0,-1,-2] if nDiff_filt=2 is chosen.
Default changed: fRepeat_clu=0 (previously 1)
Repeating clustering is not necessary if lower feature dimension is used (nPcPerChan=1).
Default changed: delta1_cut=0.6 (previously 0.5) if lower feature dimension is used.
Improved auto-merging based on mean unit waveforms using interpolation
Unit waveform similarity matrix is computed by finding the maximum correlation score
by relatively time-shifting waveform pairs after interpolating 4x in time.
Bugfix: Diagonal waveform similarity is calculated correctly after merge and subtract
Reduced the peak memory use by 50%. Spike waveforms are directly saved to the disk.
fRamCache = 1; is set to default, which stores both the raw and filtered spike waveforms in RAM.
Setting "fRamCache = 0" will only load either raw or filtered spike waveforms in RAM to save space.
