simultaneous fitting i.v. bolus and infusion data

From: Bei Yang Date: January 10, 2011 technical
Dear NMusers, I wanted to pool IV bolus and 10-min infusion data and fit them together. My question is how should I set up data item "RATE" for IV bolus? Should I leave it blank for IV bolus (since RATE is needed for I.v. infusion)? Any input is deeply appreciated. Best, Bei Yang
Dear Bei Yang, "RATE = 0" indicates that the dose is an instantaneous bolus dose.

Hi Bei, Bolus doses are indicated using RATE=0. You can use either a zero or a blank in the field. I prefer the explicit zero to the implicit zero (i.e. blank), but there should be no difference as far as NM-TRAN is concerned. Cheers... Brian
