Figure Lengend Snippet: MIMI Workflow : Detailed workflow illustrating input and output file formats for Preprocessing (mimi_cache_create) and Mass Analysis (mimi_mass_analysis) steps. Snippets of input abundance files and cache files for two independent Preprocessing runs are shown for the default natural atomic isotope ratios (blue headers; to identify metabolites in the test sample) and for an override file specifying \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$95\%$$\end{document} 13 C-labeled compounds (green headers; for the IROA-IS spike-in). In the cache files, natural minor isotopes for H and N are indicated in blue font; minor isotopes for C are in red font ( 13 C for natural ratios; 12 C for the spike-in). One or more cache files and MS peak lists (after calibration and peak picking; pink/orange headers) may be used as input for a single Mass Analysis run. A partial results table shows the layout for a run using both cache files and two sample replicates (data for the second replicate would appear as a second set of columns to the right). The same color scheme highlights output columns for corresponding inputs. The top row of the final output file contains the file path and name of the log file, which records metadata on how each workflow was run
