name, NeuroExplorer will add "event" at the beginning of the name.


<timestamp> is a number representing the neuron firing time (or event time) in seconds or in time
ticks.


Here is an example of a text file with the timestamps represented in seconds:

Neuron01 0.01

Neuron01 0.3

Neuron02 0.001

Neuron02 0.05

Neuron01 0.5

Neuron02 0.1

Neuron02 0.4

3. Multicolumn text files with continuous data


NeuroExplorer can also import continuous data from a multicolumn text file where each column
corresponds to a continuous variable:

ContChannel1 ContChannel2

114.74609 -63.47656

56.15234 -358.88672

-187.98828 -63.47656

-48.82813 388.18359

-26.85547 285.64453


The columns may be separated by any number of spaces, tabs or commas.


When you import continuous data from text files, the following dialog is shown:


First line contains variable names – if this option is selected, the fields of the first line of the text file
are used as variable names. The second line in the file is the first row of data.


First Data Point Timestamp specifies the timestamp of the first data point in each continuous
variable.


Time Between Data Points specifies the time step used in calculation of the timestamp for each row
of data. For data row N (N = 1, 2, …) in the text file, the timestamp is calculated using the following
formula:

DataRowTimestamp = FirstDataPoint + (N-1)*TimeBetweenDataPoints
