Here's a description of the rates analysis using TDCs. This is basically for my own reference, but if it is of any help to anyone else, I'll be happy!
So here goes:
On your ifarm account, jcache the required data file (e.g. e01015_2277.dat.0) from the tape to the cache.
$ jcache /mss/halla/e01015/raw/e01015_2277.dat.0
You can also copy it on your local directory using the jget command. Just that jget has the lowest priority (so it seems), and only you (and your "group") can use that file, as opposed to files in the cache, which others can use too!
After you get the file onto the cache, run the analyzer from your working directory (/work/halla/e02013/disk1/kolarkar/replay/) and execute any one of the analyzing scripts: onlana.C or physics.C. (Make sure all the paths are set correctly within the scripts.) The script will take it's own time to execute (tea-time??). When done, run the TDC_veto.C script (for the vetos) and TDC_n20.C (for the neutron detectors) to get the rates !! Simple (yeah, right!)!
Note: The farm machine will most likely NICE your process, since it takes more than 30 minutes to complete. Simply ignore it!
