You can read more about iCDF and how to analyze chromatographic data here. (2008) Solving fundamental problems in chromatographic analysisĪnalytical and Bioanalytical Chemistry, 390 (1): 281-285 If you use iCDF for MATLAB we would appreciate a reference to the program. Write 'which iCDF' to make sure you call the right function using iCDF_load. This file is NOT an m-file and thus if you type help iCDF the icdf (stats toolbox) will open. The rows correspond to the records associated with a variable. The columns of data correspond to the variables. data cdfread ( 'example.cdf' ) whos data Name Size Bytes Class Attributes data 24圆 23904 cell cdfread returns the data in a cell array. Our iCDF file must be written like this iCDF (capital CDF) to be able to work. Read All Data from CDF File Use the cdfread function to read all of the data in the CDF file. If you also have the stats toolbox there will a function called icdf that is NOT related to this program.
When you start to install the program ( iCDF.msi) the files will be placed in the folder:Ĭ:\Program Files\LIFE\iCDF Matlab ToolboxĪdd this folder to the path in Matlab and run the program in Matlab by typing or type help iCDF_load for information of input and output: Agilent, Bruker) and many chromatographic software packages (e.g. ICDF can be used to open netCDF files from many different instruments (e.g. ICDF is currently for XC-MS data (X: GC, LC, HPLC), but soon it will be able to import data using other detectors as well. In order to stimulate research in advanced chemometric data analysis, a free and documented toolbox, iCDF, has been developed, which makes the import of data a simple operation.
None of these solutions, however, are accessible to laymen.
An often cited netCDF toolbox for MATLAB version 6 uses rather advanced features but also commercial black box environments and licensed software are available. However, the transfer to other software packages is not straightforward and requires advanced toolboxes and often basic knowledge in programming. The most common chromatographic format is a so-called netCDF format, which is a format that most manufacturers of chromatographic software support.
