Tellervo Manual

The primary tool for helping you get started with Tellervo is the Tellervo user guide. It is available as a PDF download, or can be browsed below. If you prefer a hard copy, it can also be purchased as a print-on-demand softcover book. Although it is not a comprehensive guide to the software, we do our best to balance developing new features and keeping the documentation up-to-date.

The manual provides a good introduction to the Tree Ring Data Standard (TRiDaS). An understanding of the concepts of TRiDaS is important to help you to use Tellervo to manage your collection efficiently. If there are particular parts of the documentation you feel are incomplete or missing please get in touch and we'll try to fix it.

Screencast Tutorials

Another method for learning how to use Tellervo is the set of screen cast video tutorials. These take you through some of the main features of Tellervo and show them in action.

Known issue tickets

Tellervo is constantly under development. If you are waiting for a known issue to be resolved you can keep track of progress by visiting the Tellevo Ticket System. This contains a list of the known issues and for which milestone they are scheduled to be fixed. If you have found an issue that is not currently listed you can submit a ticket and you will receive notifications when it is fixed.

Frequently Asked Questions (FAQ)

Finally, we have compiled a list of frequently asked questions. If you don't find an answer to your question please contact us.

How do I get access to Tellervo server?

You need access to a Tellervo server to make the Tellervo desktop application useful. You can connect to a colleagues Tellervo server if you are working together on particular samples in which case they should give you the URL of their Tellervo server webservice. Most likely though, you'll need to install a copy of Tellervo Server on your own computer, or a server in your lab. The first time you run the Tellervo desktop application a startup wizard will ask you for the URL of the Tellervo Server you want to connect to. Enter the URL here, or alternatively you can enter it later in the Tellervo desktop preferences screen.

Is Tellervo really free?

Yes. Tellervo is released under the General Public Licence v3 which means it is free for all to use. In addition it means you have the right to use and modify the source code as long as you also make your code available under the same license. See the GNU website for more information.

What is the relationship between Tellervo and Corina?

The development of Tellervo began in 2007 from the existing Corina codebase. Corina uses a more traditional file-based data storage system. Although you may notice a few aspects of the old Corina interface in Tellervo, large portions of the code have been rewritten. Although Corina is no longer actively developed, it is still used by some people for chronology building purposes. To avoid confusion the database-enabled Corina has therefore been released with the new name 'Tellervo'.

What measuring platforms does Tellervo support?

Tellervo can currently communicate with Velmex, Lintab and Hensen measuring platforms. Support for Velmex has been tested for the standard QuadraChek and Boeckler boxes. Due to intellectual property issues claimed by Rinntech, Lintab platforms are currently only supported through the optional ASCII adapter provided by the manufacturers. If you have a measuring platform that is not currently supported, please get in touch with the developers as the architecture of Tellervo means that implementing additional platforms should be a relatively quick and easy task.

Can Tellervo be used for crossdating and chronology building?

Tellervo includes most of the functionality to enable you to build chronologies, however, we have been concentrating on the measurement and curation features for the first releases. At the moment the interfaces for managing crossdating still needs a little work. By all means have a go, but you'll probably be happier with your existing chronology build tools for now.

I don't see a Windows or MacOSX installation package for Tellervo Server. Does this mean I can't run the server software?

Although all the tools required for running Tellervo Server are available for Windows and MacOSX, unfortunately unlike the desktop client, there is no easy way of building these packages. Building these manually would be too time consuming for a small development team, therefore we have decided concentrate on building Tellervo Server for Linux. You can however, still run the server on Windows and MacOSX using VirtualBox. This runs a trimmed down version of the Ubuntu Linux operating system with all the Tellervo software preinstalled as a program within your normal operating system.

How is Tellervo different from other dendro software?

The other dendro applications that we are aware of use a traditional file-based method for storing data and metadata. Tellervo, on the other hand uses a modern relational database management system to store both data and metadata. This provides a whole host of benefits in particular it means the integrity of your data is ensured at all times. For instance if you have 50 files of data for a particular site in traditional dendro software you will have had to enter the name of the site (as well as associated information) separately for each file. In Tellervo you enter the site information just once and then you reference this whenever you need to. Any changes to this information are therefore automatically picked up by all series for that site. Tellervo is also the first desktop application to implement the Tree Ring Data Standard (TRiDaS). This means you are storing your data and metadata is standardised format which can be easily shared with other laboratories.

Is Tellervo a replacement for my current dendro software?

As we develop Tellervo further we hope to incorporate more and more features so that it is capable of doing most if not all of the operations you currently do in other software. However, we are taking one step at a time, and for the short term we are concentrating on making Tellervo a key tool for measuring and managing your dendro collections.

How can I contribute to the development of Tellervo?

We warmly encourage contributions from anyone interested in improving Tellervo! If you have experience with Java (or other modern programming languages) there are always tasks that you can work on, including self-contained features that could be implemented as a student research project. Even if you're not a programmer, there are many other ways you can help including documentation, tutorials, artwork, translations etc. Please get in touch to discuss.

What languages is Tellervo available in?

At the moment Tellervo is primarily aimed at English speakers. The infrastructure is in place to implement translations and we have started filling these in for a number of languages. Where a translations is not available it will default back to English. Tellervo will detect the language of your operating system and use this if available. Much of the translation has been done using Google Translate therefore you may find that some of the translations are a bit odd. If you prefer you can force Tellervo to use another language by going to Edit - Preferences - Appearance. If you would like to help make Tellervo available in your own language, please get in touch.

The server URL ( is not accessible. What should I do?

It appears as though you skipped the step for setting up the network adapter in your virtual server. You need to change the network adapter for your virtual server in the VirtualBox server settings to 'Attached to Bridge Adapter' and restart your Tellervo server. At the command line you should configure the webservice again by typing 'sudo tellervo-server --configure'.
