Our Tutorials
During our iGEM summer we have learned some skills which are useful for iGEM and also for any synthetic biologist. In order to conservate and spread this knowledge we created some How To Tutorials. We hope that these Tutorials help iGEM teams in the future to present their project in a more colorful fashion.
Wiki tips & tricks
Below is a list of iGEM wiki related tips and tutorials for future teams.
Picture viewer
Maybe you have not noticed it yet, but if you clicked any of the pictures on our wiki, you were not redirected to the ugly wiki page of the file. Instead a nice picture viewer opened and after you closed it, you did not have to go back to the site you saw the picture on. To get the same effect on your wiki follow the steps listed below:
- Get the files!
We modified the original slimbox 2 viewer to work with the wiki and to not exceed the browser viewport, so it is recommended to use our versions, which can be found at Team:TU-Munich/TUM13_slimbox2.css and Team:TU-Munich/TUM13_slimbox2.js. - Embed the files in your wiki!
The two files mentioned above and [http://jquery.com/ jQuery] have to be embedded on all the pages that should use the picture viewer. - Include the autoload code block!
A bit of JavaScript code that attaches the viewer to the right pictures needs to be executed on all the pages that use it. This code attaches the picture viewer to all images on the page which are embedded with the[[File:xxx.png|thumb|caption]]
wiki code and it adds the corresponding caption to the viewer.
$(document).ready(function(){ $("div.thumbinner > a img").slimbox({/* Put custom options here */}, function(el) { url = el.src; if (url.indexOf('thumb') != -1) { url = url.substring(0, url.lastIndexOf('/')); url = url.replace('/thumb/', '/'); } description = $(el).parents("div.thumbinner").children("div.thumbcaption").text(); return [url, description]; }, function(el) { return (this == el); }); });
- Test it!
Below is an example picture, click on it to see what the picture viewer looks like.
Slideshow
To create a good looking slideshow just follow the instructions below:
- Get the files!
You can get the Stylesheet and Javascript for the slideshow either from [http://bxslider.com/ bxSlider] or from our wiki: Team:TU-Munich/TUM13_bxslider.css and Team:TU-Munich/TUM13_bxslider.js.
- Embed the files in your wiki!
The two files mentioned above and [http://jquery.com/ jQuery] have to be embedded on all the pages that should use the slideshow.
- Include the initializing code block!
A bit of JavaScript code that activates the slideshow needs to be executed on all the pages that use it. This code changes all unordered lists of the class bxslider into slideshows.
$(document).ready(function(){ $('.bxslider').bxSlider({ responsive: false, auto: true, autoHover: true }); });
- Add the slideshow to the page!
To add a slideshow just put the pictures you want to include in an unordered list like shown below:
<html> <ul class="bxslider"> <li><img src="https://static.igem.org/mediawiki/2013/9/97/TUM13_slider_team1.jpg" /></li> <li><img src="https://static.igem.org/mediawiki/2013/3/30/TUM13_slider_team2.jpg" /></li> <li><img src="https://static.igem.org/mediawiki/2013/3/30/TUM13_slider_moos.jpg" /></li> <li><img src="https://static.igem.org/mediawiki/2013/6/66/TUM13_slider_kampen.jpg" /></li> </ul> </html>
- Test it!
Below is an example picture, click on it to see how the slideshow looks.
Generation of Animated Gifs showing PDB files in 3D
The generation of animated Gif from PDB files was done sice some time in the iGEM competition. Here we present an easy to reproduce tutorial for iGEMers which are interested in such figures.
- If there is no PDB file availible for your protein of interest, you may use a homology search to find the most homologue structure. For this homology search you have to enter the amino acid sequece for example into [http://toolkit.tuebingen.mpg.de/hhpred HHpred]
- The entry for the best matching structure was used for the figure. If it is only a homologous structure please cite this together with the homology when presenting the resulting Gif.
- You can save the PDB file of the homologous structure on your computer
- If you do not have [http://www.pymol.org/ PyMol] (freeware) installed on your computer download and install it.
- Start PyMol software and open the PDB-file by clicking File>Open
- The following approach was adapted from a PyMol-Tutorial http://ihome.cuhk.edu.hk/~b102142/pymol/pymol_tutorial.html Wong
- The following commands were entered into the command line:
PyMOL> orient
PyMOL> hide everything, all
PyMOL> show cartoon, all
PyMol> bg_color white
click> Settings>Rendering>Shadows>Occlusion
PyMOL> color purple, ss h; color yellow, ss s; color green, ss ""
PyMOL> show surface, all
PyMOL> set transparency, 0.75
PyMOL> set surface_quality, 1 (command will prolongue the process significantly, you may skip it)
PyMOL> set ray_trace_frames=1 (command will prolongue the process significantly, you may skip it)
PyMOL> mset 1 x180
PyMOL> util.mroll 1,180
PyMOL> mpng frame
- Afterward the *.png files were automatically converted to *.tif files using [http://www.xnview.com/de/xnconvert/ XnConvert]
- The program [http://www.animake.de/gif-animation.htm Animake] was used to generate the annimated GIFs
- The Animake software was started
- A new working folder was generated (File>New) and the *.gif files were imported (Edit>Import_from_file)
- The background was set to white (Annimation>Settings)
- The range of colors was set to 256 (Edit>Select_all and Edit>Change_Color)
- The size of the file has to be reduced in order to be able to upload it on the iGEM wiki. This can be done by clicking Edit>Change_size. We suggest a size of 320x240 px or even samler if the resulting Gif becomes to big.
- Finally the annimated Gif can be saved in the programm format (.abp) and as Gif (File>Save_as)
- If you have problems to upload the file on the iGEM server you may try a reduced size (e.g. 300x225 px)
Setting up a basic Arduino measuring device
Introduction
Since the Arduino Due was released in autumn 2012, this is the first IGEM-year this very powerful device can be used. We found it a useful supervising tool for short- and long-time experiments. It can be used in as well as outside the lab. The improvements that were made from Uno to Due are considerable.
It is capable of handling many things at once, such as a WiFi Shield, a Display, a SD-Card and multiple Sensors. At this point the Uno didn't match up any longer.
To establish the usage of Arduino in IGEM even more we'd like to share our experiences and help you building up a basic device that can collect and view sensor data on its display and upload them to a server.
Part Description
Arduino Due
The Arduino Due is the most powerful Arduino board. It's underlying 32bit-processor is the Atmel SAM3X8E. Contrary to the other boards which run at 5V, a power supply of 3.3V is sufficiant. It was released in October 2012.
Data:
84 Mhz CPU Clock 96 KBytes of SRAM. 512 KBytes of Flash memory. 54 Digital I/O Pins 12 Analog Input Pins 2 (DAC)Analog Outputs Pins
Arduino WiFi Shield
The Arduino WiFi Shield is an attachable shield that provides Wireless LAN 802.11b/g to the Arduino. It scans and connects to networks and opens TCP and UDP sockets for data transfer. It also supports WEP and WPA2 encryption. It was released in August 2012. The WiFi Shield is fully supported by the Arduino Due and Arduino supplies a suitable stock WiFi-library. There is also an on-board SD-card socket to store received data. As the SD-card is accessible separately, it can also be used as a storage for any data generated by the Arduino. The SD-card socket is also supported by a stock library. The communication between Arduino Due and the WiFi Shield runs via an SPI/ICSP interface.
Pin usage:
Pin 4 SS for SD card (Slave Select) Pin 7 Handshake between Arduino and WiFi Shield Pin 10 SS for WiFi Pin 74 SPI MISO (Master in, Slave out) Pin 75 SPI MOSI (Master out, Slave in) Pin 76 SPI SCK (Serial clock) gnd 3.3V 5V
Watterott mega msd-shield
The mega msd-shield was designed by Watterott and consists of a couple of components. The components are one real time clock, one SD-card socket (we won't use), a small battery and a socket for a touch display. To get it ready to run, the shield must be assembled. The stackable headers and the clock's quartz must be soldered to the board and the battery must be inserted. Unluckily the mega msd-shield and therefore also the MI0283QT-9 touch display don't come with a working library for the Arduino Due. The existing library only supports all boards up to the Arduino Uno. Therefore all libraries have to be rewritten. The touch display and the SD-card-slot communicate with the Arduino Due via SPI/ICSP. The real time clock transmit its data via I²C.
Pin usage:
Pin 4 SS for SD card Pin 6 SS for the touch of the touch display Pin 8 reset LCD Pin 9 LCD LED Pin 20 RTC (real time clock) I²C SDA (Serial Data Line) Pin 21 RTC I²C SCL (Serial Clock) Pin 25 SS (7) for the LCD (Workarround of the double usage of pin 7 by the WIFI Shield) Pin 50 SPI MISO Pin 51 SPI MOSI Pin 52 SPI SCK gnd 3.3V
Display MI0283QT-9
The MI0283QT-9 is a multicolor touch display. It comes already attached to a board, where only the pin headers are left to be soldered. Once assembled it can easily be plugged into the mega msd-shield. It has an on-board touch controller (TI ADS7846). The display size is 2.83"(43.2 x 57.6mm) with a resolution of 240x320. It supports 262k colors. The pin usage is already considered in the mega msd-shield description.
Light sensor TSL2561
The light sensor is a small, so called, breakout board. It is usually connected by wires instead of directly plugged into the Arduino's headers. The light sensor has two photo-diodes on-board that measure visible and infrared light. Similar to the RTC, the TSL2561 is addressed via I²C. Once you get the I²C library working on your Arduino Due working it takes only little effort to integrate additional I²C devices. Just very few lines of the library have to be rewritten here. The photo-diodes can be addressed separately or both at one. Their output is already converted to Lux.
pin usage:
Pin 20 TSL2561 I²C SDA (Serial Data Line) Pin 21 TSL2561 I²C SCL (Serial Clock) gnd 3.3V
Temperature sensor DS18B20
The temperature sensor is embedded into a water proof cable. It is addressed via a One-Wire interface. The provided data are digital raw data, which need to be converted into degrees Celsius. Information about the conversion are given by the manufacturer. Similar to the I²C (TwoWire) bus, you only have to get the One-Wire interface working once. After that, you can easily set up more One-Wire devices. Again, just very few lines of the library have to be rewritten.
pin usage:
Pin 14 One-Wire DS18B20 (pin was randomly chosen) Pin gnd Pin 3.3V
Water sensor
Setting up the water sensor is very easy. If and how much water the sensor registered can be measured via an analog pin.
pin usage:
Pin A5 Water sensor gnd 3.3V
Photo-diodes
We disassembled a broken "Biorad 550"-photometer and recovered a halogen lamp, a small number of wavelength filters, three of eight photo-diodes and their fitting Resistors.
Tools
- Breadboard
- Soldering bolt
- Solder
Assembly
Keep everything clear during your assembly. If you have different colored linking cables, always try to use the same color code. For example: red cable for 3.3V etc. Troubleshooting can get nasty.
All steps you need to follow building up your own Arduino measuring device are explained below in the slide show and the image descriptions.
For more explaining photos visit our photo gallary. On the left you see the Arduino as it boots up, connects to a WiFi hotspot and collects current data.
Code
We strongly recommend the usage of Microsoft Visual Studio with the "visual micro" plugin. Microsoft Intellisense helps you a lot, when you are unfamiliar with the manufacturer provided libraries (automatic code completion). In order to compile the code properly you need the latest beta version of [http://arduino.cc/en/Main/Software Arduino's software]. In the visual micro settings, choose the path to the Arduino IDE on your hard drive, also disable "Upload using programmer". In the settings of the Arduino IDE, select "use external software".
Now you are ready to start programming. We'd like to share our code. Feel free to use, edit and play around with it! But wait first you need our libraries! They're exclusively fitted to the Arduino Due, mostly based on the existing manufacturer's libraries for the Arduino Uno.
Assumed you followed our tutorial until here. Once you adapted the code to your WiFi and server settings and uploaded it to the Arduino it does the following:
- it starts up and the screen turns from black to white
- if you have pressed the screen, the calibration process starts
- it searches for networks and displays the total number of found networks on its screen
- it displays up the first six WiFi stations that were found
- it tries to connect to the WiFi station you have set
- if a connection was established it shows the Arduino's IP address and the SSID (name) of the WiFi it is connected to
- then it idles until you you press the screen
- after you pressed the screen it humps to the "loop"-section of the code
- it continuously runs and displays:
- the current time
- the temperature
- the measured infrared and broadband light
- the measured values of the photodiodes
- the coordinates of the point you pressed on the screen
- it builds up a connection to a server, calling a php script, passing on the collected data

Libraries
Since it's not possible uploading files of the type file.h or file.cpp, we zipped our libraries, named the suffix .zip.txt and uploaded THEM to the wiki. To unzip the libraries simply remove the .txt. We're very sorry but it was simply to much code to locate it as text on our pages. Unzip the archive into your ./arduino/libraries folder.
The data generated by the Arduino was stored on a web server. For this purpose the Arduino sends the data sets in a GET request to the server, where a PHP script (save.php) stores them in a MySQL database. To view the data, another PHP script(index.php) retrieves the data from the MySQL database and plotted as a chart by utilising the JavaScript chart library [http://nvd3.org/ NVD3]. To view the data from our Arduino visit [http://igem.wzw.tum.de/arduino/].
