Re: Problem with addfiles?

They are different because the first set is 5 files of 10 years each, and
the second set is 50 files of 1 year each. The code is in a loop d = 0,364
to get a single day from all 50 years. So the first set gets 10 records
(d::365) per file, while the second gets only 1 record (d) per file and so
doesn't need the stride. The first concatenates the five groups of 10
records, as shown in printVarSummary, while the second does not, resulting
in only 1 timestep instead of 50. I can add the stride to the second set to
see if it then concatenates, but shouldn't it work as written?
