DAFCAT User's Guide =========================================================================== Last revised on 2010 JUN 03 by B. V. Semenov. Abstract -------------------------------------------------------- DAFCAT is a command-line utility program that concatenates together SPICE DAF files of the same type. Summary -------------------------------------------------------- DAFCAT is a program for concatenating several DAF files of the same type into a single (new) file. For example using DAFCAT you can concatenate several SPK files into a single file; concatenate several CK files into a single file; or several binary PCK files into a single file. However, DAFCAT does not allow you to concatenate different types of DAF based files into a single DAF file. For instance, you cannot concatenate a C-kernel and SP-kernel together using DAFCAT. DAFCAT concatenates the source files in order they are provided on the input. For each source file the segments are copied to the destination file in the same order as they are stored in the source file. The program does not alter the data from any of the segments in any way. If some of the input files contain overlapping data, the data from the file that appears last in the input list will be stored closer to the end of the output file and will be accessed first by the SPICE Toolkit. DAFCAT does not put any information into the comment area of the output file. It is the responsibility of the operator of the program to prepare comments for the output file and to add them to the file using the COMMNT utility program (see commnt.ug for details). Usage -------------------------------------------------------- DAFCAT takes a list of files to concatenate from standard input and concatenates them together in a new file that is listed on the command line. Thus if the text file "sources" contains a list of files to be concatenated together and you wish the combination to reside in the file "grouped.daf" enter the command dafcat grouped.daf
