read header information by readtable
Show older comments
Hi,
I want to read the header information of a data file, like this:
EDFversion : 0
PatientID : B0018
RecordID : 02
startDate : 29.04.98
startTime : 23:18:00
headerSize : 4352
reserved :
numberDataRecord : 9711
dataRecordDuration : 3
numberSignals : 16
How do I read variable names and their values in coloumn with different data format -- some are strings, some are date & time, some are empty and some are double? Thanks in advance!

is it a text file or an excel file?
The EDF Version header suggests that it is EDF format. There are functions to read EDF files, such as edfreader()

you can try to use the 'Format' field in the readTable function where you are going to read each column with a differnt format
app.meas_table = readtable(yourFile,'Format','%s%d%f');
In this case I'm going to read the first column as a string, the second as a integer and the third one as a float
%d: integer
%s: String
For the date format I suggest you to read it as a string.
Let me know if it works

Format can only be used for text files, and at the moment we do not know the file format.
