Using MicroManager 2.0g, we've noticed that a large time series (7,000 frames) takes a very long time to start acquiring when run from the MDA window. When we click Acquire, the image window appears but the illumination shutter does not open. After >1 minute, the shutter opens and the image sequence is acquired normally. A single snap is essentially instantaneous, and stacks of 70 or 700 frames start without a noticeable delay. Based on this, my hunch is that MM is struggling to pre-allocate memory for the large stack, but I don't know enough of the details of how the MDA code works to try to troubleshoot. This behavior was first observed with a Nov. 2019 build but we upgraded to the Feb. 20 nightly build and it didn't change anything. Thanks for any suggestions. Dan Dickinson UT Austin |
