Random starting point in SRN sequences

[Tim Rogers <timr@mrc-cbu.cam.ac.uk>]

Hi folks,

	I've got a SRN learning various 25-step sequences.  Rather than always 
presenting it with a complete sequence during training, I'd like to begin each 
training sequence at a random starting point (e.g. begin at step 16 and run to 
the end).  Seems like I should be able to muddle with the initialization of 
the sequence process, to set the tick.val and cur_event.index fields to a 
random starting value each time the processes is initialized.  Unfortunately, 
can't figure out how/where to do this.  Can I tell the processes to call a 
script when it is initialized?  Do I need to write some code and recompile 
(would prefer not to as I am running from precompiled binaries currently and 
anticipate difficulties compiling on my current machine).

	TR
