LIAS metabolites - NaviKey Module for Identification - Lichen substances

LIAS metabolites – Identification of lichen substances

LIAS metabolites is a lively project with growing scientific information and data richness. It is maintained by an editorial team.

If the LIAS metabolite database has been of some use in your work, please consider to cite it as follows:

We also would appreciate your feedback.

For identifying lichen species of the world, consult LIAS light.

For usage of the database, the instructions for Standardized Thin Layer Chromatography by Elix and Ernst-Russell (1993) should be followed. Our MS Excel sheet 'LIAS metabolites Calculator' may probably be of help.

LIAS metabolites data are available for interactive identification purposes using three kind of services described below: DiversityNaviKey Progressive Web App (PWA), NaviKey Java applet (no longer recommended) and offline use with NaviKey offline tool and DELTA files.

DiversityNaviKey

DiversityNaviKey (DNK) is a tool primarily designed for diagnosis and interactive identification of organisms or other items as well as item groups which are part of or related to biodiversity, geodiversity or environmental research (see About).

Current versions of the PWA give access to six data sources, among them LIAS light and LIAS metabolites (see here).

Start using the tool by opening https://divnavikey.snsb.info in a browser on any user device (desktop, tablet, smartphone). Select the appropriate data source (LIAS light, LIAS metabolites) and proceed as recommended.

NaviKey

The embedded NaviKey applet is actually working only with Mozilla Firefox versions up to 51.0.1. and Mozilla Firefox ESR (32-bit) versions up to 52.9.0esr. Other language versions might be accessed below the platform of the respective program version, e.g., https://ftp.mozilla.org/pub/firefox/releases/52.9.0esr/win32/.
Automatic updates should be disabled in the Firefox settings to keep the working browser version.
Be aware that use of legacy versions of browsers is recommended only for visiting reliable websites.
NaviKey applet may be blocked because it does not fully comply with security guidelines implemented in Java 7 Update 51. You can use the Exception Site list feature to run the applications blocked by security settings. Adding the URL http://liaslight.lias.net to the Exception Site list allows NaviKey to run.
For offline usage of LIAS metabolites data, download NaviKey and keep yourself updated with the most recent LIAS metabolites data files. Unpack the data files and copy them into the local ../NaviKey_xxx/DeltaSampleData/ directory.

To run the applet, the most recent version of Java™ Runtime Environment needs to be downloaded and installed first. Mac OS X users may load Java for Mac OS X. For usage of the context menu, Java v. 6.0 or above is required. The address of this web site (http://lias.net) needs to be included in the list of allowed sites of the web browser's pop-up blocker settings. Detailed instructions are provided further below.

An interactive key using

Usage of the applet:

top left – Character panel: selection of characters.
top right – Character states or numeric data panel: preselection of states of the selected character. For selecting more than one character state at the same time, press the <CTRL> button plus the respective character states. (To finalize the query for a selected character, click the <Select> or <Add> menu button and then persue the identification process with another character.)
bottom left – Query criteria panel: display of previous character state selections. It is possible to deselect a previous choice by selecting it and subsequently pressing the <Remove Selection> button.
bottom right – Matching items panel: display of matching items (selecting any item will bring up a complete description of that item).

For offline usage of LIAS metabolites data, download NaviKey and keep yourself updated with the most recent LIAS metabolites data files. Unpack the data files and copy them into the local ../NaviKey_xxx/DeltaSampleData/ directory.
