TDT System

Structure of TDT System

Data are mainly stored in tdt.streams and tdt.epocs.

• Streams standardized naming rules:

  • All data is stored using four capital letters, e.g. UDLP, DBSS and STPD.

  • Starting with capital letter U represents Utah array recordings, e.g. UDLP are utah array data recording in DLP.

  • Starting with capital letter U represent DBS recordings, e.g. DBSS are DBS recording in STN.

  • STPD, TASK and EYET represent startpad signal, 4-bit event task codes and eye tracking data.

• tdt field Description

tdt field	sub-field	description
epocs	Cam1	Cam1/2: onset and offset time of each frame
	Cam2
streams	UDLP	Utah array data recordings in dorsolateral prefrontal cortex (DLP) [n_chns, n_temporal]
	UMCX	Utah array data recordings in motor cortex (MC) [n_chns, n_temporal]
	UPMC	Utah array data recordings in premotor cortex (PMC) [n_chns, n_temporal]
	DBSS	DBS recordins in STN [n_chns, n_temporal]
	DBSG	DBS recordings in GP [n_chns, n_temporal]
	EYET	x,y positions of eyes from eye tracking system [2, n_temporal]
	TASK	4-bit event codes from GoNogo/COT task program. [4, n_temporal]
	STPD	Startpad signal [1, n_temporal]

Example dataset: Barb-220324Block-2

NWB Structure Storing TDT data

Stored in NWB.acquisition	Structure in tdt	Description
‘tdt_neur’	Neur	neural data
‘tdt_stpd’	Stpd	synchronization signal from the touch pad.
‘tdt_eye’	EYEa	x,y positions of eyes
	EYEt	sync data from eye tracking system

Folder Naming for Storing TDT data

All recorded raw tdt data should be stored under folder rawTDT with the subfolder structure like rawTDT\animal-yymmdd\Block-#.

Example folder structure:

rawTDT\Barb-220324\Block-1
