Source code is input to compiler or any other translator. Performance of object code is more than source code as it is more close towards machine. Performance of source code is less than object code as it is less close towards machine. It contains more number of statements than source code. It contains less number of statements than object code. It does not contain comments for understanding by machine. It contains comments for better understanding by programmer. It is written in machine language through compiler or assembler or other translator. It is written in a high-level language like C, C++, Java, Python, etc., or assembly language. Object code is machine understandable and executable. Source code is not directly understandable by machine. Object code is translated code of source code. Source code is written in plain text by using some high level programming language. Object code is generated by compiler or other translator. Source code is generated by human or programmer.

MS/MS Spectra corresponding to a peak group are combined to form a consensus spectrum, which is then searched against spectral libraries to identify compounds ( E). The peaks picked from individual sample EICs are then associated with their corresponding peak groups ( D). Peak groups are defined by overlapping regions of intensity in merged EIC. These merged slices are used to generate extracted ion chromatograms (EICs) and summed to form a merged EIC. Slices from all samples are merged based on overlaps in m/ z or RT space ( C). MS/MS scans collected in LC/MS run are used as seeds for formation of “slices”-blocks in m/ z and retention time (RT) space surrounding the MS/MS scan’s precursor m/ z ( B). Outline of key steps and novel algorithmic implementations are highlighted in blue ( A). MAVEN2 implements MS/MS-based slicing, construction of consensus spectra, and spectral library matching. Overview of MS/MS-based workflow in MAVEN2. GUI fragmentation identification lipidomics metabolomics open-source software visualization. MAVEN2 source code and cross-platform application installers are freely available for download from GitHub under a GNU permissive license, as are the in silico lipidomics libraries and corresponding code repository. To support our improved lipid identification workflow, we introduce a novel in-silico lipidomics library covering major lipid classes and compare searches using our novel library to searches with existing in-silico lipidomics libraries. We explore the ability of our approach to separate authentic from spurious metabolite identifications using a set of standards spiked into water and yeast backgrounds. We have developed algorithms to support MS/MS spectral matching and efficient search of large-scale fragmentation libraries. This manuscript describes a major update to the program, MAVEN2, which supports LC-MS/MS analysis of metabolomics and lipidomics samples. As mass spectrometry has advanced in the intervening years, MAVEN has been periodically updated to reflect this advancement. MAVEN, an open-source software program for analysis of LC-MS metabolomics data, was originally released in 2010.
