newBrukerMCFReader {rtms} | R Documentation |
Open a Bruker multi-acquisition MCF directory
Description
Creates an RTMS reader object (of class rtmsBrukerMCFReader
) which can
extract data from a Bruker multi-acquisition directory (extension ".d")
Usage
newBrukerMCFReader(mcfdir)
Arguments
mcfdir |
A directory (usually with the extension ".d") containing data from a Bruker multi-acquisition run. This directory will contain a files with extenssion ".mcf" and matching index files with extension ".mcf_idx" (see Details). |
Details
Currently, RTMS can create reader objects for two binary Bruker data formats, BAF (presumably standing for "Bruker acquisition format") holding data from a single spectrum acquisition, and MCF (probably "multi-acquisition container format") containing data from multiple spectra acquired in a single run. Both formats hold data in a directory marked with the extension ".d". The multi-acquisition MCF format directory contains four essential data files: the main raw data file ending in "_1" with extension ".mcf", a matching index file with extension ".mcf_idx", and a calibration data file ending in "_2" with extension ".mcf", and the matching calibration index file with extension ".mcf_idx". This function preprocesses the main index file and calibration files so that raw data can be extracted quickly on demand from the main ".mcf" file.
An important note: when a MCF multi-acquisition reader is created, it creates
an open connection to the raw data file, which allows for quicker processing
of many spectra in a single file. This connection will remain open until
the reader is closed with the close
function.
Value
A reader object of class rtmsBrukerMCFReader
with an open
connection to the main ".mcf" data file.
