Frequently Asked Questions
Can I subscribe for a group of people?

Yes. We offer special rates for groups, laboratories, classrooms, departments, sites, computing centers, etc.

In case of large groups, we also offer convenient subscription management methods for administrators.

Please send us an email at sales@oneangstrom.com to learn more.

Can I subscribe to a plan and paid extensions at the same time?

Yes. When you want to subscribe to a plan and multiple extensions at the same time, we may offer reduced rates. Please contact us for more information.

Which plan should I use for teaching?

The free Starter plan may be sufficient to teach about atoms, molecules, proteins, etc.

To teach more advanced topics (e.g. protein-ligand docking, molecular dynamics simulations, etc.), you should subscribe to the Standard plan. If you want your class to use SAMSON as well, please send us an email at sales@oneangstrom.com for special rates.

Can I switch plans after I start a plan?

Yes. Sign in and go to My Account, click the Manage plan button, then select the plan and the period you would like to switch to.

If you switch to the Standard or the Professional plan, the unused part of your previous plan will be reimbursed.

In case you switch to the free Starter plan (which amounts to cancelling your plan), your subscription will be stopped but your current plan will remain active until the end of your billing period (when cancelling, any started period is due).

If you would like to switch to an Enterprise plan, please contact us at sales@oneangstrom.com.

Can I really cancel my plan anytime?

Yes, absolutely. Sign in and go to My Account, click the Manage plan button, then click on the Downgrade button that will show up in the free Starter plan.

Any started period is due, and your plan will be active until the end of your billing period.

For example, if you start a monthly Standard Plan on November 1st and cancel on November 10, your plan will be active until November 30. On December 1st, you will go back automatically to the free Starter Plan, and you will not be charged anymore (your last payment will have been on November 1st).

Can I try the Standard plan without being charged?

Only the yearly Professional plan can be tried without being charged.

This is risk free, however, since you can cancel anytime during the 30-day trial period and you will not be charged anything.

Can I get some training for SAMSON as well?

Absolutely. We offer training for using SAMSON as well as for developing extensions for SAMSON.

Please contact us to tell us about your needs.

Can you develop extensions for me?

Yes, we definitely can. We provide custom development services and can create extensions - sometimes within days - tailored to your exact specific needs in a very cost-effective way.

Upon your request, these custom extensions can remain private and exclusive to you in order to preserve confidentiality and retain competitive advantage.

Please contact us for a confidential discussion about your needs.

Do I have to subscribe to extensions too?

No. All extensions are optional. Many extensions are free, though, so feel free to add them.

Moreover, paid extensions can still be tried for 30 days without a credit card.

Do I have to purchase computing credits as well?

No. Computing credits are only needed for some extensions which perform calculations in the cloud. If you do not use such extensions, you do not need computing credits since all calculations will be performed locally, on your computer.

I am developing extensions. Do I need a paid plan?

No. You can develop extensions with the free Starter plan.

In case your extension needs features that are not available in the free Starter plan, however, you will need to subscribe to a plan that includes the feature you need.

I would like to get feature X. What should I do?

There are multiple options. You can ask us to add it. You can develop it yourself using the free SAMSON Software Development Kit, and you can ask other developers to create new extensions and upload them on here.

I have another question. How can I contact you?

Please send us an email at sales@oneangstrom.com and we'll reply within 24 hours.
