Format

.xlsx file with header metadata and six columns and 7943 rows:

Column 1

Sample index (divide by sample rate for seconds).

Column 2

tHb: total haemoglobin concentration change (\muM).

Column 3

HHb: deoxyhaemoglobin concentration change (\muM).

Column 4

O2Hb: oxyhaemoglobin concentration change (\muM).

Column 5

Event marker (character).

Column 6

Unmarked event label (character).

Channels are detected automatically from the file legend (the unmarked label column is named "labels"), or can be specified explicitly for read_mnirs():

• nirs_channels = c(THb = 2, HHb = 3, O2Hb = 4)

• time_channel = c(sample = 1)

• event_channel = c(event = 5, label = "labels")
