The cost of the 2 day User Group Meeting is $500 for corporate attendees and $250 for academics.

For the training day (either/both tracks) the costs are $550 for corporate attendees and $275 for academics. Training attendees can attend either track. The fee for the training day does not include the user group meeting fee.

The cost includes all breaks, lunches and the social programs.

We look forward to welcoming you in May.


The Hotel Novotel Centrum Budapest will host our UGM in Budapest. Note that the hotel tends to fill quickly so reserve accommodation early. Book your room online now by visiting this page.

Note that besides the ChemAxon conference rate you will find cheaper offers too from the Novotel. The reason is that our conference price includes breakfast and cancellation fee (you can cancel your booking 10 days prior arrival), while the other prices do not. You can decide not to have these options included into your room reservation, and book your accommodation on your own.

Application focus training

May 24th, approximately 9:00 am - 5:30 pm in the event hotel. Runs concurrently with Developer Training Day track

Application focus training is designed mainly for end users (chemists and biologists) and those new to ChemAxon, to get a handle on basic functionality and how you can interact with it. The morning session introduces key technologies and features, it introduces ChemAxon technology in general. The entire afternoon session is dedicated for hands-on training and workshops for advanced and new users too. For more details see the agenda below.

Since the training will have hands-on part you will need to bring your own laptop or let us know if you want to get a loaner for the training day. Also you will need to download and install the recommended software and licenses to your desktop (for the exact details please re-visit this page later). All attendees will get a free license valid for all ChemAxon products. The session starts at 9.00 am but we will be helping attendees set up their machines from 8 am.
