export table from statistics collector after each experimenter run

Dear all,

After each experiment run, I would like to export a table from a statistics collector to my harddrive by running a script from the experimenter (advanced\end of replication). I can find the node 'data' of the collector in the tree, but I don't know how to export this to a csv or excel file. Does anyone know how to do this? Thanks in advance!

FlexSim 18.0.1

As you have discovered, Statistics Collectors automatically record data during an experiment. To access that data after an experiment, you can use a Calculated Table:

SELECT * FROM Experiment.MyStatisticsCollector

Once it's in a Calculated Table, you can make charts of the data, or export all of it. You can also change the query to filter, sum, average, or otherwise manipulate the replication data.

@jordan.johnson Ive found that when I do an experiment with, say, 50 replications, I end up with an enormous table with data for all 50 replications in it. Is there a way to export data after each replication for just that replication? Or to delete the table´s contents after exporting to start with a clean table for the next replication?

It depends on how you want to export. If you export to Excel, I don't know a way to do that from the child processes. However, you can read this article on how to export data from child processes to a database.

Hey Jordan!
Do you have an example of a Statistics Collector export onRunStop?
I tried the following (without success) :

Table table = Table.query("SELECT * FROM MyStatisticsCollector)

exporttable (table, "outputFile.csv"); //an already existing csv file

Thanks!

I don't think you can export Tables that are the result of a query. I think you need to pass a bundle or treenode table.

I can't remember what stuff works in 18.1. You may also be able to directly pass a Statistics Collector, like this:

exporttable(Table("MyStatsCollector"), "file.csv")

Give that a shot. Let me know if it doesn't work.
