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.

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.
