.SH NAME
	spike2sdf -- compute SDF (spike density function).
.SH SYNOPSIS
	spike2sdf \fBfname\fR \fBperiod\fR \fBsigma\fR \fBrestrict_window\fR
.B
.PP

.SH DESCRIPTION
.PP
Spike2sdf computes spike density function for a spiking timeline, sampling
every \fBperiod\fR using a Gaussian with \fBsigma\fR considering
spikes from \fBrestrict_window\fR msec centred at sampling point.

SDF is calculated as a sum of exp(\- dt_i^2 / sigma^2), where dt_i is
sampling point to spike time distance.

.SH SEE ALSO
