Data acquisition during a week with triggers

Hi,

I'm searching how I can be program some .m file in order to acquired some data during a week, and only I want save a piece of data (during one minute after the trigger occurs).

I've studied how perform the trigger and which types of triggers there are.

In the "Configuring Analog Input Triggers" explains how save data when a trigger occurs and you can specify how many triggers do you want to occurs. In my case, I want specify the lasted the listening of the channel (a week), how long I want to save the data (1 minute after the trigger occurs) but I don't know how many triggers occur (it depends on number of electrical signals that the sensors detect).

Can you help me how I can develop this adquisition?

Thanks,

While a week long program might work, I think that is pushing the limit to how long most people keep MATLAB running for ...

Hi,

I've found the follow command may be it's a good way to solve my problem.

set(ai, 'TriggerRepeat', inf);

I know that I need to put the 'stop' command in order to do a correct data acquisition, but I don't know how I control the total duration of the data acquisition. In most examples, the variable 'duration', when we use the trigger's commands, means the duration of the system listening the channel after the trigger occurs, no the total time of this listening. How I can control the total time?

Thanks
