HiSeq2000 - Next Level Hacking



We got a HiSeq 2000, Next Level Sequencing Machine from the Genomics Facility of Department of Biosystems Science and Engineering in Basel. Contact through Biozentrum, University of Basel. We got it for free with the only disclaimer: "The biohackers should understand that they are responsible to organize and pay for the transport as well as that there is no warranty or support that can be given neither by us nor the DBSSE." This type of machine seems to be quite difficult to get up and running and also reagents, flowcell-kits and software licences can be expensive. Since more of these machines seem to show up in second hand (there are new machine generations by Illumina) it would be worth trying to find a way to make them work. Sequencing for all. Specifications: https://www.illumina.com/documents/products/datasheets/datasheet_hiseq2000.pdf The HiSeq2000 (200Gb) was introduced in the year 2010. Followed by HiSeq2500 (500Gb) in 2012. And HiSeq X Ten (1000Gb) in 2014. In 2017 the NovaSeq series of machines was launched. The machine is a quite early on, from March 2011, Serial Number is 700792, so the machine can not be updated to software and chemistry v4. Only machines with SN# 7001403 or higher can get the FPGA update v4.

First Inspection
I made a first inspection on the machine. It seems very well made (2011). I still think it would be cool to make it run as is. It's basically a big microfluidic system. So if we get the pumps and the cameras to work we can hack it into anything we want 🙂. Even if it's not for sequencing - it's basically a holder for flow-cells with a fluorescence camera attached to it. And 16 channels with pumps and selector valves that attach to the flow cells. Plus a fridge and a computer. And peltier for heating and cooling (pcr). Now trying to get the control software. I also think the system is "relatively" open... the software can be downloaded and kind of installs, there is no ID checking on the supplies or anything. Looks very hackable. Also all the cases can be opened easily. Let's do a weekend hack-session on it. I think it's great opportunity to learn about next level sequencing and about how theses machines work. Fluidic System: Some pictures from the inside of the machine:

Lausanne Bio-Hackerspace Hackuarium got a HiSeq2000 (SN# 700918) and Gustavo dissected it. Here some pictures that Rachel sent me with comments form what I think components are:

Control Software
Our machine with SN# 700792 can not be updated to HiSeq Control Software (HCS) v2.2.37 or higher. Possible options are (depends on software on the FGPA, how to find out?): On the "do not eject" virtual drive from the machine it looks as if the last update was: override_2013-08-21__05_11_55.cfg So that was just after releas of HCS 2.0 The HiSeq instrument computer employs 64-bit Windows Vista.

Dell Precision T7500 Tower-Workstation AMD FirePro V3750 256MB 48 Giga Ram http://euro.dell.com/content/products/productdetails.aspx/workstation-precision-t7500?c=de&l=de&s=corp http://www.dell.com/support/article/us/en/4/sln291329/precision-t7500-windows-xp-and-windows-vista-driver-install-guide?lang=en#Broadcom57XXGigabitControllerDriver All the drives were removed from the computer when we got it. There is a raid controller board, an ethernet card and the Phoenix Video Card installed in the machine.

Unfortunately the computer has a problem with the power supply and does not start up properly and we need to press the button on the powersupply to get it going somehow. The Phoenix PCI Express x1 The screen comes with a touch screeen interface.

Software Installation
We had to completely reinstall the control computer. All the files needed to get the machine up and running could be found (2018) as free downloads on the internet. Here is how:
 * First install Windows Vista
 * Install the ethernet driver, the grafics card driver and the Chip-Set Driver from the Dell Support Hompage (links below)
 * Install the HiSeq Controll software (in our case we guessed Version HCS 2.0, depends on the FPGA version and SN of the machine) using the install.bat
 * The connect the HiSeq and turn it on, wait for 2 minutes until all the serial device show up
 * Then had to install the FTDI2xx64 driver for the USB serial ports from the FTDI website (for Windows Vista)
 * Also had to put a copy of the FTDI2XX.dll in the Illumina/ControlSoftware folder. (why?)
 * Install the Camera driver DCAM-API v15.10.4787, https://dcam-api.com/downloads/
 * Reboot
 * Also put a copy of the camera.dll into the Illumina/ControlSoftware folder (not sure if needed).
 * Then the software keeps asking for an "Override" file on C:, so I copied to "Override_xx" file from the "DONOTEJECT" drive of the machine to C: and renamed it to "override.cfg"
 * Also the software needs drives up to E: for data / setting storage (just used some USB sticks)
 * Then start the control software and wait for the initialization to complete.

Using the System with Recycled Chemistry and FlowChips
We were able to get some SBS chemistry (V4) and some used chip form a sequencing lab (Unil Lausanne). For every run that labs do there is about 15-20% chemistry left over and as there is only one flow chip contained in each kit, the chemisty can not usulay be used anymore. We also got some used flow chips that were allready processed. We managed to load the cheistry into our machine and start a sequencing run. (even thoug our machine is not suitable for V4 chemistry). The machine would first do a lot of pupming, then adjust to focus of the microscope in the corners of the flow chip and then start scanning the flow chanels by tiles and using the different lasers.

We set the software to store the scanned images: Dumped (compressed) image showing fluorescence of T bases.

Challenge: If there was a way to 'clean' to reuse them, cheap DIY sequencing would be possible usine left over chemistry and chips collected from a sequencing lab.

The fluorescent readout system with lasers and CCD cameras
Patent by Illumina: https://www.google.com/patents/DE202011003570U1?cl=it The HiSeq uses an epifluorescence microscope design shown in the diagram. Light of the excitation wavelength is focused on the specimen through the objective lens and the fluorescence emitted by the specimen is focused back the detector by the same objective. Here you can see the two camera units with even the letters A G T C written on it. The laser calibration sheets that came with the machine:

The readout system of the HiSeq uses Line Imaging:

The Flow-Cell
The recommended maximum cluster density is 750,000-850,000 clusters/mm² when using Illumina's v3 cluster generation and sequencing reagents in combination with HCS v1.4. That makes 866²-921² clusters or 1.08-1.12 um² in average per cluster.

Some rough calculations/estimations on what is going on in the machine
The DNA clusters are about 1 Micrometer in size. (or bigger for older machines/software, maybe 2-5 um) The lines on the flow cells are about 1 mm large what means 1000 clusters. (Or lager, up to 1.7 mm) The reading speed is about 1mm per second or 1000x1000 clusters per second. Or 1 Mega bases. The lines are 6 cm long and there are 10 lines per flow cell.And two flow cells. The means 600 Mega Clusters (Bases) per flowcell per complet run. And that takes about 600 seconds or 10 minutes. Then flush the flow-cell to add the next base (SBS, sequencing by sythesis). Then start over again. Unitl the whole 150 bases long DNA sequences are read. This takes about 4 days... 10 Genoms. The cluster are red in 4 colors / letters at the same time through 2 lasers exciting 4 colors in fluorescence. By 4 CCD line cameras with Time delay and integration (TDI). Line cameras with 1 micrometer resolution, 1000 lines a second. Or 1 picture 1000x1000 per second... The chemistry cost some hundreds to some thousands... but for what it does its not so bad. And you get the chemistry kit with the flowcell. So all the magic and the rest is just some kind of state of the art open hardware 🙂

The HiSeq commands were extracted form the Control Software Log files. This file is created with every action of the software and contains a lot of information on what is going on, including the commands sent to the different devices via virtual serial port, set values and feedback from the machine.

Using the HiSeq2000 as aFluorescent Scanning Microscope
With many of the commands known it is possible to use the HiSeq2000 as a transmission or fluorescent scanning microscope. We developed a simple control software based on PureData to send commands to the HiSeq control hardware and get images from the scanning microscope. To view, set-up and read the scanner cameras we used HCImage software and TDIScan tool both available for free from Hamamatsu.

OpenSeq / Discussion
The goal is to make it work! Let's discuss on the forum.. http://forum.hackteria.org/t/hiseq2000-next-level-hacking/325/1 - Where to get/buy the reagents and flow cells - Hackquarium Lausanne got a similar machine and dissasembled it. We can get pointers from Gustavo on how to take it all apart! - Muffatto there's a fluorescence microscope inside (afaik), the issue is to reduce it in size and still have it working - Muffatto: erik from biocurious reverse engineered the chemistry of the system for BGI - Bengt: Absolutely in on building an openseq kind of thing that can run original reagents. And then re-engineering the system for smaller/cheaper/simpler - even better if combined with an effort to make open reagents - but that is 2 tracks that can progress independently

How about making an Open Source Next Level Sequencing machine - OpenSeq. Maybe a bit slower and smaller.. like 1 genome per day 🙂 Not sure a price tag of 500k euro is justified for such a machine... Maybe similar to the iSeq100: https://www.illumina.com/systems/sequencing-platforms/iseq.html
