Description Usage Arguments Details Value Author(s) See Also Examples

This is a CompTox SDF Export-specific wrapper function for MetFragConfig.

1 2	MetFragConfig.CompToxExportSDF(mass, adduct_type, results_filename, peaklist_path, base_dir, CompToxSDFtoLocalSDFterms, ...)

`mass`	The mass with which to search the candidate database (`DB`). Use `neutralPrecursorMass` and `adduct_type` to set whether this is monoisotopic mass or an adduct species. Defaults to `adduct_type`.
`adduct_type`	The adduct species used to define mass (if `neutralPrecursorMass=FALSE`) and fragmentation settings in the config file, entered as either `PrecursorIonType` (text) or `PrecursorIonmode` (a number). The available options are given in the system file `MetFragAdductTypes.csv` in the `extdata` folder. Recommended default values (if ion state is unclear) are `[M+H]+` (1) for positive and `[M-H]-` (-1) for negative mode.
`results_filename`	Enter a base filename for naming the results files - do not include file endings
`peaklist_path`	Enter the full path and file name to the peak list for this config file
`base_dir`	Enter the directory name to set up the subfolders for MetFrag batch results. If the folders don't exist, subfolders `config`, `log` and `results` are created; the output of this function is saved in `config`.
`CompToxSDFtoLocalSDFterms`	The output of `CompToxSDFtoLocalSDFterms`, used to set `DB, localDB_path, UDS_Category and UDS_Weights` in `MetFragConfig`

Remaining parameters are described in MetFragConfig

Returns a MetFrag config file name
