XCMS Online
XCMS Online is a cloud version of the original XCMS technology (a bioinformatics software designed for statistical analysis of mass spectrometry data), created by the Siuzdak Lab at Scripps Research. XCMS introduced the concept of nonlinear retention time alignment that allowed for the statistical assessment of the detected peaks across LCMS and GCMS datasets. XCMS Online was designed to facilitate XCMS analyses through a cloud portal and as a more straightforward (non command driven) way to analyze, visualize and share untargeted metabolomic data. Further to this, the combination of XCMS and METLIN allows for the identification of known molecules using METLIN's tandem mass spectrometry data, and enables the identification of unknown (uncharacterized molecules) via similarity searching of tandem mass spectrometry data. XCMS Online has also become a systems biology tool for integrating different omic data sets. As of January 2021, thXCMSOnline/METLIN platform has over 44,000 regis ...

The X Window System core protocolRobert W. Scheifler and James Gettys: ''X Window System: Core and extension protocols, X version 11, releases 6 and 6.1'', Digital Press 1996, RFC 1013Grant EdwardsAn Introduction to X11 User Interfaces/ref> is the base protocol of the X Window System, which is a Computer network, networked windowing system for bitmap displays used to build graphical user interfaces on Unix, Unix-like, and other operating systems. The X Window System is based on a client–server model: a single Server (computing), server controls the input/output hardware, such as the Computer screen, screen, the Computer keyboard, keyboard, and the Computer mouse, mouse; all application Computer program, programs act as client (computing), clients, interacting with the user (computing), user and with the other clients via the server. This interaction is regulated by the X Window System core protocol. Other protocol (computing), protocols related to the X Window System exist, both bu ...
