After all this, if you want to read in data without the aid of a catalogue, there is the command

xsel >  read event filename

If no data directory has been set you will be prompted for one. You can enter the files by hand on the command line, or dump their names to a file, say file.lis, and give @file.lis as the filename to the read command:

xsel > read event "@file.lis"

The double quotes are necessary to keep XPI from expanding file.lis onto the command line (q.v. @ in XPI section).

There are several other functions which give more information about the data. To view the contents of the Event, or GTI files that have been entered, use the command

xsel >  show event,gti

To see a list of the data read in, use the command

xsel >  show data

To view the contents of the work or data directories, use the commands

xsel > list workdirectory


xsel > list datadirectory

Finally, to clear the data use

xsel >  clear data
