Dear All,



I have .raw files from iTRAQ and I'm a trying use the isobar bioconductor package. The input file formats for this package is csv and mgf formats. I was able to convert my .raw files to mgf format (using Proteowizard/msconverter) and .raw to mzXML format.  Does anyone have any suggestions on what tools to use and how to convert my files to csv format? I am new to proteomics data, so any insight will be appreciated. Thanks! Below is my session info:

There isn't any utility provided by the developer of isobar. You have to export the data and write your own tool to format it into the required columns.
