Q: What data must be excluded to prevent the inclusion of any individually identifiable personal information.
Users affirm that there dataset uploaded to the BfNIRS Cloud does not include any individually identifiable personal information, including names, zip codes, dates of birth, acquisition month and date and any other personal identifiers including
Identifiers That Must Be Removed to Make the Data Set De-Identified
(B) All geographic subdivisions smaller than a State, including street address, city, county, precinct, zip code, and their equivalent geocodes, except for the initial three digits of a zip code if, according to the current publicly available data from the Bureau of the Census:
(1) The geographic unit formed by combining all zip codes with the same three initial digits contains more than 20,000 people; and
(2) The initial three digits of a zip code for all such geographic units containing 20,000 or fewer people is changed to 000.
(C) All elements of dates (except year) for dates directly related to an individual, including birth date, admission date, discharge date, date of death; and all ages over 89 and all elements of dates (including year) indicative of such age, except that such ages and elements may be aggregated into a single category of age 90 or older;
(D) Telephone numbers;
(E) Fax numbers;
(F) Electronic mail addresses;
(G) Social security numbers;
(H) Medical record numbers;
(I) Health plan beneficiary numbers;
(J) Account numbers;
(K) Certificate/license numbers;
(L) Vehicle identifiers and serial numbers, including license plate numbers;
(M) Device identifiers and serial numbers;
(N) Web Universal Resource Locators (URLs);
(O) Internet Protocol (IP) address numbers;
(P) Biometric identifiers, including finger and voice prints;
(Q) Full face photographic images and any comparable images; and
(R) Any other unique identifying number, characteristic, or code.
Q: How to specify NIRSCoordinateSystem in the coordsystem.json file?
keywords for NIRSCoordinateSystem in coordsystem.json are
CapTrak: RAS orientation and the origin approximately between LPA and RPA
EEGLAB: ALS orientation and the origin exactly between LPA and RPA. For more information, see the EEGLAB wiki page.
EEGLAB-HJ: ALS orientation and the origin exactly between LHJ and RHJ. For more information, see the EEGLAB wiki page.
- Any keyword from the list of Standard template identifiers: RAS orientation and the origin at the center of the gradient coil for template NifTI images
To interpret a coordinate (x, y, z), it is required that you know (1) relative to which origin the coordinate is expressed, (2) the interpretation of the three axes, and (3) the units in which the numbers are expressed. This information is sometimes called the coordinate system.
These letters help describe the coordinate system definition:
- A/P means anterior/posterior
- L/R means left/right
- S/I means superior/inferior
RAS means that the first dimension (X) points towards the right hand side of the head, the second dimension (Y) points towards the Anterior aspect of the head, and the third dimension (Z) points towards the top of the head. The directions are considered to be from the subject’s perspective. For example, in the
RAS coordinate system, a point to the subject’s left will have a negative
If the probe is generated using AtlasViewer software then use
CapTrak for NIRSCoordinateSystem. To find more information about this please refer https://bids-specification.readthedocs.io/en/stable/appendices/coordinate-systems.html.
