Release 0.5.4 of the NeuroLOG middleware has been deployed on the current partner sites: I3S, IRISA, GIN, IFR49, ASCLEPIOS. It focuses on service invocation issues, cart usage, and general user interface enhancements. GIN site has been included back into the data federation.

This release introduces web services interface breaks, therefore it is not compatible with the previous release 0.5.3. Any existing client installation must be upgraded. This release corresponds to the revision r2235 of the trunk branch, and is tagged 0.5.4.

Release 0.5.4 comes with the following changes:

• jGASW evolutions to support environment variables and miscellaneous files needs.
• Multi-file datasets can be used as input of a processing tool.
• The user cart can be saved on local computer, and can later be reloaded.
• General usability of the client has been improved.

• The Visioscopie viewer does not works on all MacOS platforms. Not available on Linuix 64.

Because grid gateway features are not fully integrated into the NeuroLOG Middleware, we still need to have a gLite user interface (UI) to perform some grid operations on EGEE. Only one gLite UI is deployed for the whole federation. Each site administrator must upload SSH credentials to connect to the gLite (UI) (menu “Administration→Grid UI credential management”). Those credentials are then used when a user generates a grid proxy in order to publish it into the gLite UI.

To perform a grid operation on EGEE, users must initialize a grid proxy :

1. menu “User→Grid proxy management”
2. upload (the first time only) the grid certificates (generally named usercert.pem and userkey.pem)
3. click on “Grid proxy init” button (the proxy is generated in the NeuroLOG server and the transfered to the gLite UI)

If you already have an up and running client, please follow the steps below:

• Download the client java archive : http://neurolog.unice.fr:64000/~neurolog-test/delivery/v0.5.4/NeuroLOG_Client-1.0-SNAPSHOT-jar-with-dependencies.jar.
• Place the client java archive into your $HOME/.neurolog/lib directory.

Refer to the first installation procedure of version 0.5.0. Then proceed with the client upgrade section above.
