Concatenated Text File Splitter
Our current solution to data archival includes concatenation of the tandem mass spectral data files produced during SEQUEST analysis (so-called "dta files" by virtue of their extension) into a single text file. This program splits these concatenated files into separate files that can then be searched via SEQUEST or other software that expect .Dta files as input. We also routinely concatenate SEQUEST analysis output files (so-called "out files") in a similar fashion. This program will split these archived results as well.
Please see the Command Line Application Help page for additional information on running this program at the Windows command prompt.

Example Concatenated Data File
The following is an excerpt from an example _dta.txt file, which was created from a series of .dta files. The Concatenated Text File Splitter program can parse this file, looking for the header lines, and create separate .dta files for each section in the concatenated file. Note that the "scan=5563 cs=2" portion of the parent ion info line is a PNNL-specific add-on to .Dta files (see Matrix Science's Data File Format page for additional information).
