v1.1

v1.1

• Added dataUnit to indexed groups aux and measurementList
• Uses of the word "numerical" were replaced with "numeric" for consistency.
• stim/data was incorrectly described as [,...]+ in the table when it should be [[,...]]+
• aux/dataTimeSeries was incorrectly described as [[,...]]+ in the table when it should be [,...]+
• aux/dataTimeSeries and aux/time were described as numeric in the document when they should be 1-D numeric array
• probe/detectorPos2D was described as numeric in the document when it should be 2-D array
• Added "Data format" section
• Specified that non-array fields must be saved using scalar dataspaces, and that array fields must be saved using simple dataspaces of the specified rank
• Specified that all strings must be saved in a variable length format
• Added writing code samples
• Removed ambiguity in the units of the nirs(i)/data(j)/measurementList(k)/sourcePower field, which were defined as both being in mW, and arbitrary. Only the latter definition is retained.
• Changed /nirs(i)/data(j)/time and /nirs(i)/aux(j)/time to specify the variable be stored as a rank-1 array, rather than a rank-2 array with a singleton trailing dimension.
• Specified that probe/sourceLabels is 2D string array. In wavelength-less case, spec describes 2nd dimension of 1
• Specified that aux{i}/dataTimeSeris is a 2D array. Multiple channels of data can be present, otherwise 2nd dimension should be 1.
• Added language preventing metaDataTags sub-groups
• Added notice that the summary table is intended to be machine-readable

v1.0

• General clarification of wording throughout the specification.
• Remove sourcePos, detectorPos, and landmarkPos.
• Add wavelengthActual and wavelengthEmissionActual.
• Change stim/data names from attribute to regular dataset.
• Require either 2D or 3D positions, not just 2D.
• Add list of supported aux name values including accel, gyro, magn
• Add datatypes for processed TD moment data.
