Netcdfreadr

Purpose

Reads in netCDF files and outputs a DataSet and or structure.

Synopsis

x = netcdfreadr(filenames, options);

Description

If no file is given (filenames) then prompts user for filename/s. Default options are set to handle Mass Spectroscopy exported data.

NOTE: This function uses netcnetCDF Library Functions available in Matlab 2009a and newer.

Inputs

• filename = a text string with the name of a spectral file or a cell of strings of filenames.
  • If filename is omitted or blank, the user will be prompted to select a file graphically.
  • If filename is an empty cell {}, the user will be prompted to select a folder and then one or more AIT files in the identified folder.

Outputs

• x = takes one of two forms:

1. If input is a single file, or multiple files containing data that can be combined (same number of data points, same x-axis range, same type of data), the output is a dataset object
2. If the input consists of multiple files, but the data cannot be combined, the output is a cell array with a dataset object for each input file (see the nonmatching option defined above)

Options

options = a structure array with the following fields:

• output :[{'dso'}|'rawdata'|'datastruct'|'all'] What output to pass.
• getms : [{'yes'}|'no'] Get Mass Spec dataset from file.
• massoffset : [0] Shift point for round-off (when using .getms).
• chunksize : [1.5] Divide data into chunks of chunksize*1,000,000 elements when contructing a MS dataset. Value of 1.5 million is good default for 32bit systems.
