Where to find the file generated by ann2rr() ?

Hi everyone, After using:

>> [rr,tm] = ann2rr('my_data', 'qrs'); The Workspace showed a variable rr with value Nx1 double. I guess a RR time series has been created. The command , as far as I understand it, writes the RR Intervals to the standard output in text format. Something like, for example, ecg01.rr1.txt.

Question: Where can I find this file containing the RR intervals? Many thanks for any help! Kind regards, Massilon

standard output is just the command line. Your result should be in the rr variable.

function varargout=ann2rr(varargin)
  [RR,tms]=ann2rr(recordName,annotator,N,N0,consecutiveOnly)

    Wrapper to WFDB ANN2RR:
         http://www.physionet.org/physiotools/wag/ann2rr-1.htm

    Reads a WFDB record and Annotation file to return:
 RR
       Nx1 vector of integers representing the duration of the RR
       interval in samples.
 tms
       Nx1 vector of integers representing the begining of the RR
       interval in samples.

The Matlab function of the same name simply returns the output to the variables; doesn't look like it creates any files; that appears to be "exercise for the student".
