Digital Event Series

Digital event series are data represented by an ordered sequence of timestamps. Examples include spike timestamps from extracellular recordings or behavioral events (e.g. go cue, reward given).

Digital Interval Series

16 bit binary representation

{
  "filepath": "ttl.bin",
  "data_type": "digital_interval",
  "name": "laser",
  "format": "uint16",
  "channel": 2, // REQUIRED, bit (0 based) for channel of interest
  "transition": "rising", //optional, 
  "clock": "master", //optional, clock signal to assign to these events
  "header_size": 0 //optional, number of bytes to skip at start of file

Element	Description	Required?	Type	Notes
filepath	Path to binary file, relative to JSON file.	Yes	string
data_type		Yes	string	“digital_interval”
name	Name of the data once it is loaded into Neuralyzer	Yes	string
format		Yes	string	“uint16”
channel	Specifies which bit in binary representation should be extracted as digital interval	No	number	Default is 0. Valid values range from 0-15
Transition	“rising” will count a TTL interval as one extending from low-to-high transitions to high-to-low transitions. “falling” will count a TTL interval as one extending from high-to-low to low-to-high transitions.	No	string	Default is “rising”. Valid values are “rising” or “falling”.
clock	Clock signal to associate with this digital interval	No	string	The clock string must match the name of a loaded clock signal.
header_size	This many bytes will be skipped at the beginning of the file before reading the rest.	No	number	Default is 0. Accepted values range from 0 to size of file in bytes.
