Trigger and Gate Express VI misses some triggers

[mhtl]

I have created a program using continuous data acquisition and the Trigger and Gate Express VI.

I am continuously streaming data in and using the Trigger and Gate Express VI to trigger off the first channel and allow a certain # of values through. The process I am monitoring is running continuously and providing a trigger about once every 1.2 seconds or less depending on the speed of the process. The program works quite well except it appears to miss a trigger about once every 15 or 20 'cycles'. By probing the trigger sequence, I can see it missing the trigger but I can't find out why - the data is there, the levels are fine, the trigger signal is very clear and clean and yet every twenty cycles or so it just m
isses seeing the trigger and skips a cycle.

The program has started working for me. I think the problem was that I was still specifying number of samples per channel to the start acquisition and read samples Daqmx subvi's. I removed these specifications and it seemed to not miss any machine cycles after this.
