to the matrix of numerical results.
Send to Matlab
An option to send the matrix of numerical results to Matlab. See also
.
Matrix Name
Specifies the name of the results matrix in Matlab workspace.
Matlab command
Specifies a Matlab command that is executed after the numerical results
are sent to Matlab.
Send to Excel
An option to send numerical results or summary of numerical results to
Excel. See also
Sheet Name
The name of the worksheet in Excel where to copy the numerical results.
TopLeft
Specifies the Excel cell where the results are copied. Should be in the form
CR where C is Excel column name, R is the row number. For example, A1
is the top-left cell in the worksheet.
Summary of Numerical Results
The following information is available in the Summary of Numerical Results
Column
Description
Variable
Variable name.
YMin
Spectrum minimum.
YMax
Spectrum maximum.
Spikes
The number of spikes used in spectrum calculation.
Filter Length
The length of all the intervals of the interval filter (if a filter was used) or the
length or the recording session (in seconds).
Mean Freq.
Mean firing rate (Spikes/Filter_Length).
First Minimum
Frequency Position
The position of the minimum of the displayed spectrum (in Hz). If there are
multiple bins in the spectrum where the spectrum value equals to the
spectrum minimum, this value represents the frequency of the first such
bin.
First Maximum
Frequency Position
The position of the maximum of the displayed spectrum (in Hz). If there are
multiple bins in the spectrum where the spectrum value equals to the
spectrum maximum, this value represents the frequency of the first such
bin.
Algorithm
Spectral Densities for Spike Trains and Events
NeuroExplorer uses rate histograms to estimate the power spectra of the spike trains. The
parameters of rate histograms are calculated using the following formulas:
Bin = 1./(2.* Maximum_Frequency )
Number_of_Bins = 2* Number_of_Frequency_Values
The time axis is divided into intervals of length Bin*NumberOfBins. Then the power spectrum for each
interval is calculated. The final raw power spectrum is the average of all the spectra for the separate
