Re: [las_users]LASv8.6.1/2 install problems

Many thanks! This indeed resolves the FER_FONTS/PLOTFONTS problem. However, the basic problem remains the same, also with las_6.8.1 and ferret_7.1. F-TDS is working correctly, but LAS comes up with no information on the coordinates of the data sets. Only coads_climatology is read correctly. Switching to the old fer_dsets does not help either.

Just to summarise and complete:
- the backends of the product server do not work. At earlier LAS versions I get some reasonable output from adresses like

This does not work any more with the new installation -> error 404.

I will be patient, until Roland is back.

Hi Martin,

I do not have much help for the odd behavior with the UI, except to say that occasionally I've found it helpful to clear the browser cache for such things.

I can address the issue with the environment variable. There is an inconsistency between LAS configure.pl and the most recent Ferret release, v7.2 which doesn't use PLOTFONTS but instead looks for the environment variable FER_FONTS. (This will be corrected in the next Ferret release.)

LAS v8.6.1 will work well with Ferret v7.1, so that is our recommendation.

Or you could edit both FerretBackendConfig.xml and FerretConfig.xml to include both FER_FONTS and PLOTFONTS.


The closing tag should be </application>. FerretBackendConfig.xml and FerretConfig.xml are both needed. They are created when you run configure.

Just to add to the previous letter:

with logging level "DEBUG" and "ERROR" enabled, it turns out, that the initial horizontal axis-span is zero for all data sets except the coads-climatology.

The LAS browser output never finishes and cannot be cancelled. In las.log:
