Raising the roof on STN limits for iterations and saved answers

Did you notice the STN double-play that occurred in April?  A two-fold increase in two STN system limits will provide you with increased flexibility when searching for and managing information on STN.

Iteration limits doubled!

If your broadly defined structure searches occasionally resulted in incomplete answer sets because they've exceeded iteration limits, we have good news for you!  You'll be pleased to learn that we are doubling iteration limits for both online and batch structure searches:

Searches Previous limits New limits
Online 1 million 2 million
Batch 1.5 million 3 million

The CAS REGISTRYSM has witnessed extraordinary growth over the past few years with approximately 12,000 new substances now added daily.  The REGISTRY database currently contains more than 45.6 million organic and inorganic substances - all potential candidates for matching your structure query.

Doubling the iteration limits will save you time as it provides greater opportunities for broadly defined structure searches to run to completion.  The increase in limits will help you maximize the value REGISTRY has to offer as the largest, most authoritative collection of disclosed chemical substance information in the world.

Saved answer limits doubled!

Are there times when your saved answers come close to exceeding STN limits?  Do you spend time deleting answers to make room for new search results?

Good news!  STN now allows you to save twice as many answers online as you previously could.  The limits for both temporary and nontemporary answer storage have doubled:

Saved answers Previous limits New limits
Temporary 500,000 1,000,000
Nontemporary 400,000 800,000

These new limits should help accommodate new answers saved from your future projects.
