Hi I am new to MatLab and wanted to know how I can plot EDF data. I have stored the data into a variable using edfread, using the following code.
plotData = edfread('testdata.edf');
The edf data looks like the following
plotData =
ver: 0
patientID: 'test '
recordID: 'test '
startdate: '23.06.16'
starttime: '12.10.38'
bytes: 9472
records: 3
duration: 1
ns: 36
label: {1x36 cell}
transducer: {1x36 cell}
units: {1x36 cell}
physicalMin: [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
physicalMax: [1x36 double]
digitalMin: [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
digitalMax: [1x36 double]
prefilter: {1x36 cell}
samples: [1x36 double]
What is the best way to plot this data?

Hi,
this is only the header file (information), to get the main recorded data as well you should import it like this:
[hdr, data] = edfread('testdata.edf');
