<i>I downloaded a .dmg, opened it, dragged and dropped GoldenCheetah into
|
|
Applications, double-clicked on it, and nothing happened. What gives?</i>
|
|
|

<p>

|
Are you running OS X Tiger? You need to be. If you are, and you're still
|
|
having this problem, open Terminal (in Applications -> Utilities) and type
|
|
this at the prompt:
|
|
|
|
<blockquote><pre>
|
|
/Applications/GoldenCheetah.app/Contents/MacOS/GoldenCheetah
|
|
</pre></blockquote>
|
|
|
|
then press <return> and send an email to the mailing list with
|
|
whatever it prints out. We'll help you debug it.

|
<i>I've downloaded and unpacked the data. Now what do I do with it?</i>
|
|
|
|
<p>
|
|
We highly recommend that you buy and read both Joe Friel's <i>The
|
|
Cyclist's Training Bible</i> and Allen and Coggan's <i>Training and
|
|
Racing with a Power Meter</i>. The former is the definitive book about all
|
|
aspects of cycling training (although we think he's off his rocker in the
|
|
chapter about diet), and the latter is the definitive book about power-based
|
|
training.
|
|
|
|
<p>
|
|
Also, if you buy either of these books through the links below, we'll get a
|
|
referral fee in return, helping us to support this web site. Thanks!

<i>Does the output of <code>ptunpk</code> exactly match that of the software
|
|
included with the PowerTap?</i>
|
|
|
|
<p>
|
|
Almost. If you run it in compatibility mode, using the <code>-c</code>
|
|
option, it matches the PowerTap software's output exactly on everything but
|
|
the time values, at least for the five sample rides we've tried it with.
|
|
The times are a little off, but not by more than 0.1%, so we don't consider it
|
|
a big deal.
|
|
|
|
<p>
|
|
That said, the PowerTap software does some weird things, like converting from
|
|
kilometers to miles by multiplying by 0.62, but then reporting the miles
|
|
values with five digits after the decimal place. If you run
|
|
<code>ptunpk</code> without the <code>-c</code> option, it will unpack the
|
|
data in the way we think it should. The results mostly match up with the
|
|
official ones, and are almost certainly identical within the range of accuracy
|
|
of the device.
