Importing Continuous Data From Text Files
NeuroExplorer can import continuous data from a multicolumn text file where each column corresponds to a continuous variable. Here is an example:
ContChannel1 ContChannel2 114.74609 -63.47656 56.15234 -358.88672 -187.98828 -63.47656 -48.82813 388.18359 -26.85547 285.64453
Use File | Import Data | Text File with Continuous Variables (no timestamps)… menu command to import such a data file. The following dialog will be 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 data row timestamp is calculated using the following formula:
DataRowTimestamp = FirstDataPoint + (n-1)*TimeBetweenDataPoints
If you have a text file with the timestamps in the first column of the file:
Time ContChannel01 0.000400 114.746094 0.000500 56.152344 0.000600 -187.988281 0.000700 -48.828125 0.000800 -26.855469
use File | Import Data | Text File with Continuous Variables (with timestamps)… menu command to import such a data file.
