Requirements for MedPC file

Set a timing variable (eg U) to the internal time to set a baseline and set another as an index placeholder (eg Y). A separate index holder is needed for each data array

#Start: Set U = BTIME, Y = 0, K = 0;

Set variables to arrays to hold times:

DIM A=9999, B=3, L=9999

Save variables as they occur into the arrays:

This example saves lick times into array L

s.s.X,
s1,
#Start: ---> s2 \this prevents licks from being recorded before initialization of the session
s2,
#R^LICK: Set L(K) = BTIME-U; Add K; ---> SX

This example saves event times and the code corresponding to the event. The element is saved as TIME.EVENTCODE. For example, OnPumpA = 11 and if OnPumpA occurs at exactly 536 seconds from start will be recorded as 268000.011

s.s.X,
s1,
#Z^OnPumpA: Set A(Y) = BTIME-U + (^OnPumpA)/1000; Add Y; --->sx
#Z^OffPumpA: Set A(Y) = BTIME-U + (^OffPumpA)/1000; Add Y; --->sx

Example File (2015-09-25_ML03)

The following codes correspond to the following events in this example:

Lick = 1 (.001)

PumpA
ON = 11 (.011)
OFF = 21 (.021)

PumpB
ON = 12 (.012)
OFF = 22 (.022)

Low concentration = 50 (0.050)
High concentration = 51 (0.051)

Shift = 52 (0.052)
