 Because the EventNtuple is a [ROOT TTree](https://root.cern.ch/doc/master/classTTree.html), it can be accessed in either ROOT or python like any other TTree.
 
 ### Getting a list of EventNtuple files

 First, get a list of EventNtuple datasets as follows:
 
 ```
-setup mu2efiletools
-mu2eDatasetList --tier=nts | grep v06_03_00
+muse setup ops
+metacat dataset list -l mu2e:nts.*MDC2025*.root
 ```
-replacing ```v06_03_00``` with the most recent version number of EventNtuple from the [Mu2e wiki page](https://mu2ewiki.fnal.gov/wiki/EventNtuple#Version_History_%26_Musings).
+You can see from the output which datasets are the most recent in ```created``` column.
 
 
 Pick a dataset from the list and to get a list of files that are already [prestaged](https://mu2ewiki.fnal.gov/wiki/Prestage), do the following:
 
 ```
-setup dhtools
-samListLocations -d --defname=nts.name.of.dataset.root > filelist.txt
+metacat query files from mu2e:nts.complete.dataset.name.root | mdh print-url -l disk - > filelist.txt
 ```
 
 Check the contents of ```filelist.txt```. If it is empty, then pick another dataset. If you have authentication errors, then consult [this page](https://mu2ewiki.fnal.gov/wiki/Authentication#Tokens) on the Mu2e wiki.

 ### Printing the EventNtuple
 
 You can print the branches and leaves of the EventNtuple in ROOT or python. From your ```filelist.txt` pick a single file and use it in the following:
