Limitations
- How large can the molecules be?
- DMax Chemistry Assistant™ is designed for small molecules, but peptides can be loaded as well. Extremely interconnected molecules, such as fullerenes, are very slow to process.
- How many molecules can be processed?
- We currently recommend not to process more than 1,000,000 molecules at once. When working with a very large compound library, some operations may take a large amount of time. We are working to further improve behaviour when loading a very large number of molecules. All current customers will receive the update when it becomes available.
- How few measurements can I get away with?
- Obviously, if you have too few measurements, the tool will not be able produce hypotheses with high statistical confidence. How few exactly that is though, depends on the complexity of your data set.
Technical Questions
- On which platform/operating system can I run DMax Chemistry Assistant™?
- See this page. In short, it runs on Microsoft® Windows® and SUSE® Linux®.
- What are the minimum requirements for the hardware?
- See this page. In short, DMax Chemistry Assistant™ runs on about any recent PC.
- Is it possible to run DMax Chemistry Assistant™ on OS X?
- Not at the moment. The more requests we get from customers, the sooner we will port the DMax Assistant™ platform to the Mac®. If you rely heavily on Macs and would like to run DMax Chemistry Assistant, please contact a PharmaDM salesperson.
- I see DMax Chemistry Assistant™ uses Java™. Doesn’t that make it slow?
- First, DMax Chemistry Assistant is not slow. In fact, it can search a huge hypothesis space very efficiently, using algorithms licensed from the universities of Oxford, Leuven, and Aberystwyth, as well as PharmaDM’s own proprietary algorithms and optimizations. You can easily configure how large the hypothesis space is that is being searched. Also, it doesn’t really hurt to search a large hypothesis space, because DMax Chemistry Assistant™ will show you the current-best hypotheses while it is still searching.
Second, we use a natively compiled library for the time-critical algorithms.
- Is DMax Chemistry Assistant™ virus-free? Is it compatible with my virus scanner?
- Short answer: Yes.
Long answer: PharmaDM always provides signed software. The PharmaDM code signing certificate is awarded by Thawte, a business unit of Verisign Inc., which is generally considered to be a well-known and trusted Certification Authority. This means that all PharmaDM software bears a verifiable (and indeed systematically verfied by the Java™ runtime) electronic signature that provides both undeniable proof of integrity and non-repudiation. Thus, you can be certain that the software indeed comes from PharmaDM, and that it has not been changed in any way since it left the PharmaDM production line.
The software cannot be tampered with, for inclusion of a virus or any other modification, or the Java runtime would automatically and without failure detect this and warn the user that the software has been tampered with and cannot be trusted.
Electronic signatures do not mean that your virus scanner is circumvented or disabled. The software is downloaded to your hard disk before it is launched by the runtime, so any real-time (which includes almost all desktop virus scanners) virus scanner has the opportunity to scan the program for viruses. Likewise, a firewall with virus scanning functionality will have the opportunity to scan the program because it is downloaded using standard HTTP.
