Gets values from a single metadata column for a respective m/z value.

Usage

GetMZMetadata(
  obj,
  mz,
  assay = "Spatial",
  metadata.column = "all_IsomerNames",
  separate = TRUE
)

Arguments

obj: SpaMTP Spatial Metabolomic Seurat Object containing annotated m/z values.
mz: Character string specifying the m/z value to return the metadata for.
assay: Character string defining the Seurat assay that contains the annotated metadata corresponding to the m/z values (default = "Spatial").
metadata.column: Character string corresponding to the @meta.data column to extract the data from (default = "all_IsomerNames").
separate: Boolean indicating whether to separate the metadata string and return a vector. Note, if TRUE the metadata column should contain values separate by "; " (default = TRUE).

Value

Vector of character strings containing the metadata for a specific mz value.

Examples

utils::str(formals(GetMZMetadata))
#> Dotted pair list of 5
#>  $ obj            : symbol 
#>  $ mz             : symbol 
#>  $ assay          : chr "Spatial"
#>  $ metadata.column: chr "all_IsomerNames"
#>  $ separate       : logi TRUE
# GetMZMetadata(SpaMTP, mz = "mz-100", metadata.column = "all_IsomerNames")

##### Example for getting metabolite annotation IDs for a m/z value
# GetMZMetadata(SpaMTP, mz = "mz-100", metadata.column = "all_Isomers")
