Hi Oksana,

 

You can set up the plugin chain like this:

 

PIL->ROISTAT1->FileHDF1

 

In the detector Attributes.xml file remove all of the entries for the statistics.

 

In the ROISTAT1 you create a new attributes XML file that uses TYPE=PARAM to add the TOTAL and MEAN for each of the 4 ROIs defined in that plugin.  The ROISTAT1 plugin will now add its attributes to those added by the PIL detector driver and they will be written to the HDF5 file.

 

You no longer need to use the ROI1-4 or STATS1-4 plugins.

 

If you use the ROI and STATS plugins then you cannot use PARAM, you need to use EPICS_PV, which can have some latency as you have observed.

Hi Mark,

 

They are interested in total counts and max_count from their 4 ROIs. ROI_Start, and ROI_SIZE I can take from “EPICS_PV”.

I understand same things can be archived with ROIStats, which would be fine too.

 

Thank you

Oksana
