Overview
:startdoc::manifest converts .dat file to ascii text
Uses the Applied Biosystems DataExplorer software to extract an ASCII spectrum from a ‘.dat’ file. Each input file should be a dat file; ascii files will be placed in the output directory, with a ‘.txt’ extension (by default the output directory is the same directory as the input file).
DatToAscii is based on the getdeascii.pl script.
