+In this recording, 'dsp_compensated_buff_errs' had a bandpassfilter (dsp) and it's lag is compensated for by Cheetah:
+-DspDelayCompensation Enabled
+-DspFilterDelay_µs 3984
+
+while the 'no_dsp_buff_errs' had no dsp:
+-DspDelayCompensation Enabled
+-DspFilterDelay_µs 0
+
+The result is that 'dsp_compensated_buff_errs' has slightl more datapoints than 'no_dsp_buff_errs'. This gives a break in current
+neo as it requires the data to have the same length.
+
+The other problem with this data are RingBuffer errors (search the logfile), which are now treated by making different segments
+per gap. Both channels with have different gap times, also causing a break in current io.

+These two channels belong to the same recording session. During the recording, one had a bandpassfilter enabled (DSP) which causes 
+a lag. Neuralynx can compensate for this (DspDelayCompensation Enabled), but this is not the case for this data.
+
+We  processed them without knowing about this, but when clustering we would see duplicate neurons with a lag, the neuron
+would be detected on both leads and not be marked as the same neuron. To prevent this one should compensate for the lag.
