Formatted Event Dump

The event dump utility (cefdmp) can display, in a readable ASCII format, events from the following sources:

event file

event builder

command format

 cefdmp [filename] [-o objectname ] [-t tag] [-u uniquetag] 
       [-s start] [-e end] [-d dictionary] [-x]

(To check for list of currently available options, type cefdmp with no arguments).

options

 x hex dump for integers (default is decimal) 

 o specify name of CODA object from which to get events / fragments 

 t select specified tag number or name (full path in event) 

 u select specified unique tag, independent of location in event 

 d specify dictionary for obtaining tag names and titles 

 s number of first record in file to dump 

 e number of last record in file to dump

example

cefdmp myfile.dat -t physics.drift

This command reads physics events from the file and dumps the drift chamber portion. An X-windows version of this program also exists, started via the command xcefdmp. Options are specified by menus, and the data structure is presented graphically as shown in Figure 3.2.
