VIEWDATA – Spike data
visualization tool
To launch the interface, type
‘viewdata’
from the MATLAB prompt.
Click on ‘Load dataset’ to load spike data. This
must be stored in a MAT-file containing either 1) a cell array named TS with
the spike times for each cell; or 2) a cell array named ISI, with the series of
interspike intervals for each cell. An example can be found in the folder ‘results_base’.
The fields ‘T_start’ and ‘T_end’ indicate
the minimum and maximum spike times found in the dataset.
A figure will show a
ratemeter plot of the mean firing rate (in 1-s bins) for the two cells indicated
in Channel A (top) and Channel B (bottom).
Press ‘Switch View’ to display in turn,
- the
instantaneous firing rate (reciprocal of interspike interval) vs. the
spike number,
- the interspike intervals vs. the spike number,
- the instantaneous firing rate vs. the spike times.
Press ‘Raster plot’ to display the spike times of all the cells in the interval
[T_start, T_end],
Selecting ‘Linked to A’ will show only the raster
plots of the cells which are neighbours of A in the topology of the oxytocin
network model.
Different colours indicate a
double (red) and a single (blue) dendritic connection.
Note: for the latter option to
be functional, the datafile must contain additional information in the form of
an adjacency matrix.
