========
VKMZ 1.0
========

VKMZ is a metabolomics prediction and vizualization tool which creates van Krevelen diagrams from mass spectrometry data. A van Krevelen diagram (VKD) plots a molecule on a scatterplot by the molecules oxygen to carbon ratio (O:C) against it's hydrogen to carbon ratio (H:C). Classes of metabolites cluster together on a VKD [0]. Plotting a complex mixture of metabolites on a VKD briefly conveys untargeted metabolomics data.

**Input Data**

VKMZ is designed to use XCMS [1] data as input. Tabular data can also be used as input.

*XCMS* mode requires three files which XCMS generates: the data matrix, sample metadata, and variable metadata files.

*Tabular* mode requires a tab delimited file with the first five columns being: sample_id, polarity, mz, retention_time, and intensity.

**Advanced Input Options**

*Override polarity* allows users to set the polarity of all features to either positive or negative. This option should not be used if data contains both polarity types.

*Disable mass adjustment* prevents converting charged masses to neutral masses. If you are using neutral mass data this option should be used.

**Prediction Options**

For each feature in the data VKMZ attempts to predict a molecular formula by comparing the feature's mass to a database of known formula masses. A prediction is made when a known mass is within a mass error of the observed mass. VKMZ finds all predictions for an observed mass within the mass error. The prediction with the lowest delta, absolute difference between observed and known mass, is plotted. Features without predictions are discarded. Using low resolution data may result in finding too many predictions per feature to be useful, especially for large mass metabolites.
 
Set *Mass error* to the mass error, in parts per million, of the mass spectrometer which collected the data. 

*Database* can be set to heuristically generated databases for unlabeled and labeled chemcials [2] or to a custom database.

**Diagram Options**

Predicted features are plotted as markers. The size of each marker is determined by the minimum marker size and a marker size algorithm. The marker size algorithms use minimum marker size as a variable.
