.xlsx file with header metadata and five columns and 20919 rows:

Column 1

Sample index (divide by sample rate for seconds).

Column 2

O2Hb: oxyhaemoglobin concentration change (\(\mu\)M).

Column 3

HHb: deoxyhaemoglobin concentration change (\(\mu\)M).

Column 4

Event marker (character).

Column 5

Unmarked event label (character).

Channels are detected automatically from the file legend, or can be specified explicitly for read_mnirs():

  • nirs_channels = c(O2Hb = 2, HHb = 3)

  • time_channel = c(sample = 1)

  • event_channel = c(event = 4)

  • interval_times = list( ## two intervals, post-exercise occlusion start = c(158, 999, 1750), end = c(493, 1333, 1961) )
