Lipidomics and Metabolomics Data Processing
XCMS Online (https://xcmsonline.scripps.edu/) is an extensively used cloud-based platform for LC-MS data processing. XCMS Online is derived from the original XCMS technology, which is also still widely used and actively maintained. XCMS Online extends XCMS capabilities to a full suite of tools for metabolomic and lipidomic data analysis. Hosted on high performance and dedicated servers at Scripps Research, XCMS Online offers high processing speeds that is easily accessed by thousands of users. Together, with a freely available R package and a cloud-based data processing, XCMS facilitates data analysis and result sharing across all vendor platforms. XCMS Online is also linked to the METLIN (http://metlin.scripps.edu) database to facilitate lipid and metabolite ID.
