Windows 10, version 20H2 is the most recently released version available. When media is updated after its original release to include additional security and non-security fixes, the month/year of the update will be reflected in the file name of the download. Jorgensen Research Group Dept of Chemistry, Yale University New Haven, CT, USA Phone: (203)432-6288 Fax: (203)432-6144 william.jorgensen@yale.edu. Take control of your R code. RStudio is an integrated development environment (IDE) for R. It includes a console, syntax-highlighting editor that supports direct code execution, as well as tools for plotting, history, debugging and workspace management.
Yale assigns all members of the community a unique identifer called a NetID, which you'll use to access many of the university's online resources and accounts. You must activate your NetID before accessing any other Yale systems. Make sure you keep your NetID password safe; do not share them with anyone else!
All Yale students receive an '@yale.edu' email account. Accounts for Yale College and most GSAS students are provided via EliApps, Yale's version of Google G Suite, which includes: Gmail, Google Drive with unlimited storage, and Google Calendar. Some GSAS students in HIPAA-covered programs or programs affiliated with the Schools of Law, Management, or the Environment may recieve an Office 365 email account instead of an EliApps account.
For instructions on how to access your email account, set up email on your mobile device, or change your preferred name or email alias, click on Read More.
Multifactor Authentication (MFA) protects your accounts in the event that your NetID password is compromised. Yale implements MFA via the DUO Everywhere service; this service is required for all Yale students. New Students received an email on July 31 with instructions on how to activate DUO Everywhere. You must do so by August 14, 2020.
Most online classes and orientation events will be conducted via Zoom. All Yale students have a Yale enterprise Zoom account; you will need to download and install Zoom on your device, then use the 'Sign In Via SSO' option to access your Yale Zoom account.
Visit the Zoom Quick Guide for setup instructions and more information.
The Student Information System (SIS) powers academic processes including course registration, financial aid, and transcript orders. It is important to add and maintain personal information such as your emergency contacts and mailing address to the system. Log in to SIS, then follow the automatic prompts to get started.
Software Library Yale
Some of Yale's digital resources are only available while on campus. If you are off-campus, you can obtain access to these resources by connecting to Yale's Virtual Private Network, or VPN.
Software
The Jorgensen Research Group has developed several programs for research incomputational chemistry and drug discovery. They are freely available to academicusers.
BOSS
BOSS (Biochemical and Organic Simulation System). The BOSS programis a general purpose molecular modeling system that performs molecularmechanics (MM) calculations, Metropolis Monte Carlo (MC) statistical mechanicssimulations, and semiempirical AM1, PM3, and PDDG/PM3 quantum mechanics (QM)calculations. The MM calculations cover energy minimizations, normal modeanalysis, and conformational searching with the OPLS force fields. Roblox download install for mac. The MCsimulations can be carried out for pure liquids, solutions, clusters, orgas-phase systems; typical applications include computing properties of a pureliquid, free energies of solvation, effects of solvation on relative energiesof conformers, changes in free energies of solvation along reaction paths, andstructures and relative free energies of binding for host-guest complexes. Freeenergy changes are computed from statistical perturbation (FEP) theory.Alternatively, the energetics of the solutes can be represented with the QMmethods. Coordinate files are input/output in PDB or mol format for facileinterfacing and display. Extensive capabilities are provided for easy setup ofthe solvent molecules from equilibrated boxes of twelve common solventsincluding TIP3P, TIP4P, and TIP5P water or from user-provided solvent boxesthat are created by running a pure-liquid simulation.

MCPRO
MCPRO performs Monte Carlo statistical mechanics simulations of peptides,proteins, and nucleic acids in solution; it was derived from BOSS, but makesextensive use of the concept of residues. Version 1.68 does not includeconformational search, quantum mechanics, or normal mode calculations. The MCsimulations can be performed in a periodic solvent box, in a solvent cluster,or in a dielectric continuum including the gas phase. Energy minimizations canalso be performed with several optimizers including conjugate gradient. NMRconstraints (NOE and torsion angle) can be added for NMR structure refinementsvia simulated annealing. Free energy changes can be computed via FEPcalculations and have been used extensively for studying protein-ligandbinding.

MOPAC Modifications for PDDG/PM3 and PDDG/MNDO
MOPAC6 is a semiempirical package for calculating physical properties ofmolecules. Its source code is written in FORTRAN 77 and is freely available.By doing a few simple modifications it is possible to add PDDG support toMOPAC while retaining backwards compatibility.
