Hi Mike:
I think that was a bug fixed in the rc2 (Oct 9) release. Can you get the latest
TDS (Version 4.1.20091109.2156) and try it?

Hello,
I’m having trouble accessing a single value that is not the first value
from the time coordinate axis from an aggregation of in situ mooring
observations.
Retreiving the first element works:
http://elvis.shore.mbari.org/thredds/dodsC/moorings/OS_M0_TS.ascii?TIME[0:1:0]
Dataset {
Float64 TIME[TIME = 1];
} moorings/OS_M0_TS;
---------------------------------------------
TIME[1]
19878.020833333332
However, requesting any other single value returns an exception, e.g.
the second value:
http://elvis.shore.mbari.org/thredds/dodsC/moorings/OS_M0_TS.ascii?TIME[1:1:1]
Error {
code = 500;
message = "NcSDArray ArrayIndexOutOfBoundsException=NcSDArray
read TIME TIME(1,1,1) 1 dataset= moorings/OS_M0_TS";
};
I can retrieve a range of values:
http://elvis.shore.mbari.org/thredds/dodsC/moorings/OS_M0_TS.ascii?TIME[0:1:1]
Dataset {
Float64 TIME[TIME = 2];
} moorings/OS_M0_TS;
---------------------------------------------
TIME[2]
19878.020833333332, 19878.0625
just not a single value that is not the first one.
Have I perhaps done something wrong in the catalog.xml? Here is the
relevant section:
<dataset name="MBARI Mooring M0 CTD String Aggregation 60-Minute

I am running version 4.1.20090930.1852 - 20090930.1852 of thredds.war.
Any help is appreciated.
TIA,
Mike
