function varargout=wrsamp(varargin)
wrsamp(tm,data,fileName,Fs,gain,format)
Wrapper to WFDB WRSAMP:
http://www.physionet.org/physiotools/wag/wrsamp-1.htm
Writes data into a WFDB annotation file. The file will be saved at the
current directory (if the record is in the current directory) or, if a using
a PhysioNet web record , a subdirectory in the current directory, with
the relative path determined by recordName. The files will have the same
name is the recordName but with a 'annotator' extension. You can use RDANN to
verify that the write was completed sucessfully (see example below). For
detailed information on the parameters described below, please see:
http://www.physionet.org/physiotools/wag/header-5.htm
Required Parameters:
tm
Nx1 vector of integers representing sample index.
data
NxM vector of integers (M channels) that will be written to file.
fileName
String specifying the file name. WRSAMP will write the signal file in
the current directory as "fileName.dat", and create a header file in the
current directory "fileName.hea" for the specified record.
Optional Parameters:
Fs
A 1x1 double specifying the sampling frequency (in samples per second per
signal) for the output signals (default: 250). It affects the output header
file only. This option has no effect on the output signal file, which
contains one sample per signal for each line of input.
gain
A 1x1 or Mx1 vector of doubles specifying gain value in A/D units per millivolt
for the output signals (default: 200). This option the output header file only.
This option has no effect on the output signal file.
format
String specifying the signal's default format (default: "16"). For
information on the available WFDB formats please see:
http://www.physionet.org/physiotools/wag/signal-5.htm
%Example-
%Read signal in raw units
[tm, signal]=rdsamp('challenge/2013/set-a/a01',[],[],[],1);
[siginfo,Fs]=wfdbdesc('challenge/2013/set-a/a01');
%Write a copy to file
wrsamp(tm,signal(:,1),'a01Copy',Fs(1),200,siginfo(1).Format)
%Check that the signals match
[tm, signalCopy]=rdsamp('a01Copy',[],[],[],1);
err=sum(signalCopy ~= signal(:,1))
