Summit RC+S raw data structure. (A) One packet of data from RawDataTD.json; each packet contains one set of timing values and a variable number of time domain samples from each streamed channel; values such as SampleRate must be converted to interpretable values (e.g., Hz). (B) One section of values from DeviceSettings.json which provides information on time domain channel settings; mode, gain values, high pass and low pass filter settings, and contacts must be decoded to interpretable values. (C) Each time series stream transmits data from the INS in packets of variable sizes using UDP; receipt verification is not performed, so packets may not be received or may be received out of order. Each packet contains one value of timing information per variable, aligned to the last sample in the packet. Each data stream transmits packets separately, with non-aligned timing information. (D) The present toolbox is compatible with raw RC+S data which are acquired in 11 JSON files. This relationship diagram depicts that information from multiple files is required to interpret the recordings. For example, interpretation of RawDataTD.json may require all other JSON files which are connected to it via arrows. Colors are used to aid visualization.
