I have existing code for a self administration study that I have been trying to alter so it can record the time interval of both active and inactive responses. I seem to be able to have it record the total number of active/inactive responses in addition to the time of infusions but not the time array of each lever response. Any thoughts?
There's a chunk of code in the programmers guide that can be used to store all events timestamped into a singe array.
Here's an example below - in this case a single array (x) codes 3 different events, denoted by 0.1 as active response, 0.2 as inactive, 0.4 as end of infusion. so 130.1 means active response at 13.0 seconds.
Alternatively, you could use Z pulses (as Zachary mentioned and as we have done for end of infusion) for active and inactive responses instead of #R^active:, etc.
- here's the link for the programmers guide (previous link was user guide) : http://www.mednr.com/pdf/doc003_MedPCProgramr.pdf
s.s.3 \state set for event array
s1,
#start: set e=1 --->s2
s2,
#R^active: add a; show 1,active,a; set x(e)=t+0.1; set e=e+1; set x(e)=-987.987--->sx \0.1 is subscript for active press
#R^inactive: add b; show 2,inact,b; set x(e)=t+0.2; set e=e+1; set x(e)=-987.987 --->sx \0.2 is subscript for inactive press
#z1: set x(e)=t+0.4; set e=e+1; set x(e)=-987.987 --->sx \0.4 is subscript for end of infusion
