<h2>Preparing your entry</h2>

<p>
Your entry needs to be prepared in a special text format, which depends on
the event you are entering:

<ul>
<li> For event 1 (Apnea Screening), download this <a
href="template-test-1">template</a>,
and replace the '?' characters with your classifications ('A', 'B', or 'C')
for the 35 records in the test set (records x01-x35).

<li> For event 2 (Quantification of Apnea), download this <a
href="template-test-2">template</a>,
and replace the '?' characters with your annotations ('A' or 'N') for each
minute during each of the 35 records in the test set.
</ul>

<p>
There are also templates for submitting results from the training set (records
a01-a20, b01-b05, and c01-c10) for <a
href="template-training-1">event 1</a>
and <a
href="template-training-2">event
2</a>, so that you can obtain unofficial scores for these records as well.
Awards will be made on the basis of results from the test set (records x01-x35)
only.

<p>
If you have prepared annotation files in the same format as the <tt>*.apn</tt>
files provided with the training set, you can download this <a
href="distill.c">program</a>
(in C source form, to be compiled with the <a href="/physiotools/wfdb.shtml">
WFDB library</a>) that can convert them to the format of either of these
templates.

<h2>Submitting your entry for scoring</h2>

<p>
Please double-check your entry before submitting it to be sure it is in
<strong>plain text</strong> format, exactly like the template files.
<em>HTML-formatted entries will confuse the automated scorer and will not be
scored.</em>

<p>
To submit your entry successfully, you will need:

<ul> 
<li> A web browser that supports HTTP uploads, such as Netscape 2.0 or
 later, or MS Internet Explorer 4.0 or later.

<li> A valid e-mail address that is known to us.  Please
 <a href="/register.shtml">sign in</a> before submitting your entry.
 (If you signed in on a previous visit, you do not need to sign in again.)
 All entries are logged by date, time, and the e-mail address of the
 entrant.

 <p>
 <b>Important:</b>  Your score will be sent by e-mail to the address you
 specify.  Please be sure that your e-mail address is entered correctly,
 or you won't be able to view your score.

<li> A password.  If you don't yet have a password, or if you
 have forgotten your password, go to the entry form (see below), fill
 in only your e-mail address, click on the "Get password" button, and a
 password will be sent to your e-mail address immediately.
</ul>

<p>
After filling in your e-mail address and password on the 
<a>entry form [link disabled]</a>,
enter the name of the file that contains your correctly-formatted entry
(you may use the <b>Browse</b> button to find it), indicate which
event you wish to enter, which data set you are submitting results for,
and click on <b>Upload entry</b>.

<p>
(If you wish to enter both events, you may do so, but you will need to
submit your entry twice, once in each format, in this case.)

<h2>Notes</h2>
<p>
If you are tempted to try submitting many entries in order to learn about
the correct classifications, why not <a

target="other">play MasterMind instead?</a>  Delivery of your score may be
delayed if you submit more than one entry per event per day.

<p>
UNIX versions of Netscape, and possibly other browsers, will allow the
user to specify a directory name in the <b>File to upload</b> field of the
entry form, but the browser will not transmit anything in this case and will
hang until the user interrupts it by clicking on <b>Stop</b>.  This behavior
is a bug in the browser and cannot be detected or avoided by the PhysioNet web
server.  Other browsers will detect and disallow attempts to upload
directories.
