Variable Variable name.

Reference The name of the reference event.

NumRefEvents The number of reference events.

YMin Minimum epoch count for this variable.

YMax Maximum epoch count for this variable.

Filter Length The length of the interval filter.

Algorithm

Let ref[i] be the array of timestamps of the reference event, ts[i] be the spike train (each ts is the

timestamp) and epochs are specified as EpochStart[j], EpochEnd[j].

For each timestamp ref[k]:

1) calculate the distances from this event (or spike) to all the spikes in the spike train:

d[i] = ts[i] - ref[k]

2) for each i:

if d[i] is inside the first epoch, increment the counter for the first epoch:

if d[i] >= EpochStart[1] and d[i] < EpochEnd[1]

then epochcount[1] = epochcount[1] +1

if d[i] is inside the second epoch, increment the counter for the second epoch:

if d[i] >= EpochStart[2] and d[i] < EpochEnd[2]

then epochcount[2] = epochcount[2] +1

and so on... .
