<FONT COLOR="dd00ff" SIZE="+1">How to Start</FONT></P>
Warning: using this early beta you will encounter bugs. However, closely following
these directions should get you up and running.<P>
1. Avida should be launched from within a writable subdirectory containing at least
the files "environment.cfg", "events.cfg", "genesis", "inst_set.default", and
"organism.default":<P>
<CENTER><IMG HEIGHT="376" WIDTH="634" SRC="pics/Picture2.jpg"></CENTER><P>
2. After launching, Avida will present a "Setup Assistant". For now, make sure that the
radio button marked "Use existing world" is selected, then click the button labeled "Next":<P>
<CENTER><IMG HEIGHT="542" WIDTH="666" SRC="pics/Picture3.jpg"></CENTER><P>
3. The Setup Assistant will ask you to select a "World" configuration file, and "Work"
directory in which Avida can store the data files that it generates:<P>
<CENTER><IMG HEIGHT="543" WIDTH="777" SRC="pics/Picture4.jpg"></CENTER><P>
4. Clicking the button labeled "Select world file" will let you choose a "world" configuration
file. We supply an example configuration file named "genesis". Select the "genesis" file by
clicking on it, then click the button labeled "Open":<P>
<CENTER><IMG HEIGHT="546" WIDTH="778" SRC="pics/Picture5.jpg"></CENTER><P>
5. The button "Select work directory" will let you choose a "world" directory in which Avida
can store the data files that it generates. We suggest using the directory "Avida 2.0 beta 0"
containing the Avida application. Select that directory by clicking on it, then click the button
labeled "OK":<P>
<CENTER><IMG HEIGHT="540" WIDTH="777" SRC="pics/Picture6.jpg"></CENTER><P>
6. Avida is now ready to begin. Click the button labeled "Finish" in the Setup Assistant:<P>
<CENTER><IMG HEIGHT="543" WIDTH="776" SRC="pics/Picture7.jpg"></CENTER><P>
7. Avida will present a "Map" window showing a single organism in the Avida world. Select
"Start Avida" from the "File" menu to start Avida:<P>
<CENTER><IMG HEIGHT="438" WIDTH="558" SRC="pics/Picture8.jpg"></CENTER><P>
8. The Avida world will be quickly populated as the original organism and its descendants replicate and experience
mutation:<P>
<CENTER><IMG HEIGHT="439" WIDTH="558" SRC="pics/Picture9.jpg"></CENTER><P>
9. Avida can be paused by selecting "Pause Avida" from the "File" menu:<P>
<CENTER><IMG HEIGHT="439" WIDTH="557" SRC="pics/Picture10.jpg"></CENTER><P>
10. Various map modes can be selected using the "Map mode" popup menu, to show for example the fitnesses of organisms
in the population:<P>
<CENTER><IMG HEIGHT="441" WIDTH="559" SRC="pics/Picture11.jpg"></CENTER><P>
Or the merits of organisms in the population:<P>
<CENTER><IMG HEIGHT="440" WIDTH="560" SRC="pics/Picture12.jpg"></CENTER><P>
11. Zoom in on an organism in the population using the zoom control and the scrollbars, then select an organism by
clicking it:<P>
<CENTER><IMG HEIGHT="439" WIDTH="560" SRC="pics/Picture13.jpg"></CENTER><P>
12. To examine this organism in greater detail, select "Instruction Viewer" from the "Viewers" menu:<P>
<CENTER><IMG HEIGHT="437" WIDTH="558" SRC="pics/Picture14.jpg"></CENTER><P>
This presents the instructions comprising the genome of the organism:<P>
<CENTER><IMG HEIGHT="673" WIDTH="779" SRC="pics/Picture15.jpg"></CENTER><P>
13. Plot one of various population statistics against time by choosing "New Plot Viewer..." from the "Viewers" menu:<P>
<CENTER><IMG HEIGHT="439" WIDTH="559" SRC="pics/Picture16.jpg"></CENTER><P>
Then choose the statistic to plot, and click the button labeled "OK":<P>
<CENTER><IMG HEIGHT="544" WIDTH="559" SRC="pics/Picture17.jpg"></CENTER><P>
The plot will update itself as Avida runs. Below is a plot of average fitness over the population versus time in
updates:<P>
