The file begins with a list of identifiers (in green) and values (in red). The identifier, Name specifies a character string that should allow the contributors to match the submitted data file to their original records. The identifiers Start and Duration define the time period during which data was recorded. The unit of time is defined by Sampling, which specifies the number of samples per second. Thus, a sampling value of 1000.0 indicates milliseconds. The final identifier, Params is followed by a list of parameter names whose values vary and thus need to be specified for each trial.

The rest of the file consists of pairs of lines, each of which corresponds to an experimental trial. The first line in a pair (in white) specifies the values for each parameter named above by Params. Values must be separated by spaces or tabs, and a newline (i.e., an end-of-line character) must terminate the line. The second line in a pair (in yellow) lists the values of the discrete signal (here, membrane voltages in millivolts). The number of values must be exactly equal to Duration. Values should be separated by spaces (or tabs) and newline characters may be used to format the data into multiple lines (unlike the case for the T1 data file format). The last value should be followed by a newline.
