NAME NetAthlon2::RAW - Perl extension to parse NetAthlon2 RAW performance data files SYNOPSIS use NetAthlon2::RAW; my $t = NetAthlon2::RAW->new (); my $d = $t->parse('Bike2009-07-02 5-54pm.RAW'); DESCRIPTION A perl module to parse the NetAthlon RAW file format. parse() will return a hash reference to the resultant data structure METHODS new() Creates a new NetAthlon2::RAW object. new() does not accept any options at this time. parse($file) Returns a hash reference with the contents of $file. Keys included are: Average Cadence Calculation of the averages of the non-zero Cadence values from the Check Points array. Average Heart Rate Calculation of the averages of the non-zero Heart Rate values from the Check Points array. Average Speed Calculation of the averages of the non-zero Speed values from the Check Points array. Used to be just the division of the Distance by the Elapsed Time, but the Elapsed Time is the time of the race, where as the Distance is the whole distance, including any warmup time. This lead to incorrect Average Speed calculations in version 0.01. Average Watts Calculation of the averages of the non-zero Watts values from the Check Points array. Cadence The overall Cadence of the training session, in miles. Check Points This is an array of each sample taken during the training session. Each array element is an anonymous hash with the following keys: Altitude The instantaneous Altitude at the Elapsed Time. Cadence The instantaneous Cadence at the Elapsed Time. Elapsed Time A calculation of when the sample was taken, based on the number of samples collected multiplied by the Sample Rate. Number is in seconds. Grade The instantaneous Grade at the Elapsed Time. Heart Rate The instantaneous Heart Rate at the Elapsed Time. Speed The instantaneous Speed at the Elapsed Time. Number is in miles per hour. Watts The instantaneous Watts at the Elapsed Time. Distance The overall Distance of the training session, in miles. Elapsed Time The time of the training session, in seconds. Heart Rate Values taken from the training session. Aerobic Threshold Anaerobic Threshold Zone 1 The highest training zone. Max Min Zone 2 The second training zone. Max Min Zone 3 The bottom training zone. Max Min Sample Rate Number of seconds between each Check Point sample. Start Time The start time of the training session, in a UNIX time_t format. VARIABLES $timeDelta Number of minutes the time listed in the file name and the time listed inside the file can vary before throwing an error. The default is 1 minute. $maxWatts The maximum watts can be, to be used in calculating the Average Watts. The default is 2000 watts. SEE ALSO http://www.whitepeak.org/Raw.aspx NOTES I believe that the field that Martin lists on his web site (www.whitepeak.org) as the Grade of the course is not. In all my testing the Grade was 0, whereas the field he listed as Unknown had positive and negative values, and looks to me to be Grade * 10, so I have implemented the code to show this deviation from Martin's documentation. Based on some empirical data, I believe the Unknown value listed after the Distance, is really Cadence for the entire time. I have added the Cadence field in addition to Average Cadence.
