mergeIMSFiles: Merge spot-level data and region spots from SCiLS

In cammiller/imagingPC: Analysis of Imaging Mass Spectrometry Data using a Process Convolution Approach

Description

mergeIMSFiles merges the two files needed to create spot-level data with coordinates. The first is the spot-level data without coordinates, and the second is the region spots with coordinates. We will use the terms spots and rasters interchangeably. Though data are collected over circular areas dependent on the laser diameter, the rasterization process makes data representation easier.

Usage

mergeIMSFiles(spotData, regionSpots, trimTops = TRUE)

Arguments

spotData	A dataset containing the spot-level data in which the columns represent m/z values, and the rows represent spots.
regionSpots	A dataset containing the region spots. This should be an exported file that only contains the spot identifiers and the x- and y-coordinates.
trimTops	A TRUE/FALSE variable indicating whether or not the top rows of each dataset should be trimmed to remove metadata before merging. If metadata exists in the top rows then trimTops should be set to TRUE to remove it before proceeding to the next step. Otherwise the metadata will ineterfere with downstream steps.

Value

A merged data frame with spot-level data and corresponding coordinates.
