Finds the nearest m/z peak to a given value in a SpaMTP Object

Finds the nearest m/z peak to a given value in a SpaMTP Object

Usage

FindNearestMZ(data, target_mz, assay = NULL)

Arguments

data

Seurat Spatial Metabolomic object containing mz values

target_mz

Numeric value defining the target m/z peak

assay

Character string indicating which Seurat object assay to pull data form. If set to NULL will use current default assay based on Seurat's DefaultAssay() function (default = NULL).

Value

String of the closest m/z value within the given dataset

Examples

# FindNearestMZ(SeuratObj, target_mz = 400.01)
