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 (\(\mu\)M).
- Column 3
HHb: deoxyhaemoglobin concentration change (\(\mu\)M).
- Column 4
O2Hb: oxyhaemoglobin concentration change (\(\mu\)M).
- 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")
