# Tutorial

The applet consists of three parts: Design, Check and Turn-to-DNA. The first allows the user to enter inputs, whereas the second and third supply the user with information about his network. Below the different parts are described in detail.

## 1. Design a logic network

A logic network can be designed by adding logical devices (via double clicking) and interconnecting them.

There are five different types of logical devices: inputs, outputs, AND-gates, OR-gates and NOT-gates. The type of a local device can be change by clicking on the combo box on the device and selecting a different type. Logical devices can be interconnected by selecting (via clicking inside the area of a device) two devices and then pressing the C key (for connect). A complete logic network has to have at least one input, at least one output, and at least one gate (AND, OR, NOT). Different devices may require different numbers of ingoing and outgoing connections (e.g. a NOT-gate requires one ingoing connection and allows for a arbitrary number of outgoing connections, whereas the AND-gate requires two ingoing connections and allows for a arbitrary number of outgoing connections; an input may not have an incoming connection, an output no outgoing connection). In addition the logic network may not include loops.

The user has to assign DNA sequences (either custom RNA sequences or sequences coding for proteins) to all input and output devices by clicking on the "Set" button of the devices.

Invalid inputs (e.g. a letter different from G, C, T, A or N in a nucleotide sequence; loop(s) in the logic network; no sequences assigned to input(s)/output(s); input or output sequences that are too similar) are reported back to the users as error messages providing a description of the errors and advices to correct the errors. The Design part can only be left when the network contains no errors.

## 2. Check the logic network

The logic network designed in step 1 can now be verified.

Logical values are represented by colors (green = true, red = false). Thus a green box represents a devices (e.g. an AND-gate) with the logical value true, a red box a devices with the logical value false. The flow of logical value can be followed by following the colored edges between the boxes.

The logical value(s) of the input(s) can be manipulated by clicking on their checkbox(es).

## 3. Turn the logic network into DNA

A set of genetic devices (categorized as input elements, switch elements and output elements) representing the logical network designed in step 1 is calculated and displayed.

All elements (besides custom RNA input sequences) consist of a Escherichia coli promoter and up to two switches and one output sequences.
