The ASCII files produced by all stages of processing can be converted to a Root format, via a utility called asc2root. To convert files from ASCII to lcd format it is convenient to use a simple front-end script which sets up the necessary environment and runs the conversion program.
Follow the instructions (coming soon!) to install the Event classes and asc2root.
To run the program just issue the command:
asc2root inputasciifile.dat outputfile.root
If you have a large number of ASCII files you want to convert to Root files, it might
be convenient to use a makefile to run asc2root. An example of a suitable makefile (for
use with gmake) is given here. This example is for zipped ascii files.
