The following script takes a series of files with comma-delimited data named 0v.csv, 10v.csv etc., extracts everything in column 4 (in my case it contains relative abundance values from MS) from row 7 to the bottom, and stores those columns in files called 0.dat, 10.dat etc.
The second column (in my case it contains m/z values) is extracted from one of the csv files, and stored in mz.x.
Next, all the .dat files are pasted together, with the columns side by side, and the mz.x data added as the first column.
The data is rotated using the rotate script I've published earlier.
A file with cone-voltage values, cv.xy, has already been prepared by hand (single column), and is pasted together with the m/z data.
