ElementName DataType Size Required ElementDescription ValueRange Notes
subjectkey GUID Required The NDAR Global Unique Identifier (GUID) for subjects which identifies a subject in NDAR NDAR*
src_subject_id String 20 Required The site or study's subject identification
interview_date Date Required Date on which the interview/genetic test/sampling/imaging was completed Required field
interview_age Integer Required Age in months at the time of the interview/test/sampling/imaging. 0 :: 1200 Age is rounded to chronological month If the research participant is 15 days old at time of interview the appropriate value would be 0 months if the participant is 16 days old the value would be 1 month
mmat_ver Float Recommended mmat version
rprtgenver Float Recommended Report Generater version
reflectors Integer Recommended number of reflectors 0 :: 3
mmperuevent_szeref Integer Recommended a new unique event begins when this amount of distance is moved. 0 :: 1000
camrastr String 200 Recommended Camera version
mtsmodel String 200 Recommended motion tracking system model
resa Integer Recommended motion trasking system version 0 :: 100
resb Integer Recommended dummy variable for future description of MTS version 0 :: 100
framesa_percent Float Recommended percentage of time reflector is detected within frame 0 :: 100
reflectorsa_percent Float Recommended percentage of time reflector is detected 0 :: 100
cptacc_percent Float Recommended Percentage of correct responses to both the targets and non-targets 0 :: 100
cpterrom_percent Float Recommended Percentage of time the patient failed to respond to the target. Omission errors measure the patient's level of distraction and/or degree of inattention 0 :: 100
cpterrcom_percent Float Recommended Percentage of incorrect responses made to the non-targets. Commission errors are a measure of the patient's impulsivity or inability to inhibit a response 0 :: 100
cptlatmillisecond Integer Recommended Mean reaction time to respond to a target 0 :: 400
cptvar Integer Recommended Variation (standard deviation) in response times to the correct target. High levels of variability indicate that the patient is inconsistent in the task performance 0 :: 1000
cptcov Integer Recommended Variability that is adjusted to take into account difference in response latency. (COV = (100 * Variability) / Latency). This is a more stringent measure of response consistency. 0 :: 100
headimobdur Float Recommended Average time not moving greater than 1 mm - based on head reflector 0 :: 5000
