Data provided by Guy Perkins 13 03 25 email guyantony.perkins@unipd.it twitter @brainimagingguy In the data folder there are NIRS measurements .NIRS files and sensor glucose concentration .mat data: 1) Structure of the NIRS data (.NIRS format) "PDN_m_hypo_N.nirs" Full information can be found at https://www.nmr.mgh.harvard.edu/martinos/software/homer/HOMER2_UsersGuide_121129.pdf PD_data.SD A field of information about the source-detector probes and device measurements. PD_data.d [N frames x N channels] The intensity of the signal. PD_data.s [N frames x N stimuli Stimulus information of the signal, this experiment has no stimuli markers. PD_data.t [N frames x 1 ] The value of the time samples of the intensity signal. 2) Structure of the sensor glucose concentration data (.mat format) "PDN.mat" It contains the following fields gap_info gap_info.start_gap the start of the gap in the glucose data (sample number) gap_info.end_gap the end of the gap in the glucose data (sample number) gap_info.delta_t_gap_Nsamples the length of each gap in the glucose data as a number of samples gap_info.delta_t_gap_length the length of each gap in the glucose data in seconds N_events The number of glycemic events for each event type events_length The length of each glycemic events for each event type (number of samples) events_start_end The start and end point of each glycemic event (sample number) glucose_data_gaps date_of_events The start and end date of each glycemic event time_of_events The start and end time of each glycemic event glucose The sample glucose concentration (mg/dL) sampled every 5 minutes.
