[las_users] need help for F-TDS data anlaysis

Hi,

We followed the exact step to install and config F-TDS with LAS.

Ferret version: 6.72

Las version: 7.3 (tested on 7.2 too)

OS: RHEL 6

Tomcat Version: 6.0.32

We are able to view

http://IP:8080/thredds/dodsC/las/coads_climatology_cdf/data_coads_climatology.jnl.ascii?SST[0:1:1][0:1:5][0:1:5]

this is working fine, we can see the values in ascii

However, when doing server data analysis, it returns error.

http://IP:8080/thredds/dodsC/las/coads_climatology_cdf/data_coads_climatology.jnl_expr_%7B%7D%7Blet%20A=SST*2%7D.ascii?A

Error {

code = 2;

message = "The variable `A' was not found in the dataset.";

};
