nmrbox.org NMRbox: TRD 3 A probabilistic core as a coherent inference engine PINE+ Core Extend functionality through the new core PINE+: Assignment, use of structure data, RNA Reproducibility – “revisable executable documentation” Side-by-side, reproducible, probabilistic and deterministic
nmrbox.org Why Bayes? argmin E total = E empirical + λE experimental Bayes: Extremizes the log-likelihood. Consistent & extensible determination of parameters Constrain: NOEs not distances. J’s not dihedrals etc. Consistency + Extensibility Reproducibility
nmrbox.org What is PINE and PINE Core? PINE is the probabilistic Bayesian engine for Data verification (LACS) Secondary structure determination (PECAN) Assignment (PISTACHIO) Peak picking (HIFI) Bayesian updating (PINE) Bayesian updating + deterministic constraints (ADAPT-NMR) RNA assignment (RNA-Pairs) LACSPECAN PISTACHIO HI FI LACS PECAN PISTACHIO LACS PECAN PISTACHIO HI FI ADAPT-NMR
nmrbox.org Corollary In our view, Pine has been a highly successful probabilistic model. The inference core has proven to be very powerful – an excellent setting for building a structure determination protocol for: Repeatability and Reproducibility Coexistence of probabilistic and deterministic paradigms Extensibility to support new functions through plugins Additionally empowering: Revisable executable documentation Document as you go, execute any time, reuse.
nmrbox.org PINE+ PINE+ is the collection of applications Containing a core probabilistic engine The core will support all existing tools HIFI, PINE, PECAN, ADAPT-NMR, LACS, RNA-PAIRS And, New assignment tools NOESY, RNA, Structure-based PINE+ will support probabilistic and deterministic approaches PINE+ Will additionally enable reproducible results Playback of blocks or the entire project (repeatability)* Edit & Replay of blocks or the entire project (reproducible)* Template (reuse)
nmrbox.org Key Innovations The complete process of structure determination is captured and executed using one language, one environment, one paradigm, in open source form, using open technologies. As the user steps through structure determination steps, a living “executable document” is created – repeatability. “Blocks” of a structure determination “document” can be modified with new data or process – reproducibility. A “document” can be used as a “template”; replacing, or modifying blocks as needed – reuse.
