BryoBrain – Description of the program




BryoBrain comes with a Setup, which will install the program in a directory of your choice. The program runs under MS Windows® 9x, ME, NT, 2000, XP. For installation under NT, 2000 or XP admin right are required.


The program

The program consists of four windows:

  • Main window

  • Image window

  • Options window

  • Help window


The main window

The buttons on the upper (gray) panel of the main window have the following functions:

The  ?  button opens the “Help window” showing information about the program.

The “Options” button opens a window where you can change some basic settings (see below).

Bryobrain is now completely bilingual (English/German). The language can be changed with the button English version/deutsche Version on the upper panel.

The Close button will close the program.

The lower part of the main window consists of a page control with five pages:

1  Intro

Shows some information about the program.


2  Table

In the lower part of the Table-Page, three fields are shown displaying attributes of the  database currently in use. These are:

  • Observation: This field is not used for classification. You can enter a name, the collection number or a short description.

  • Weight - Classification (No. of Characters): After the classification the program writes the result in this field. It cannot be changed by the user.

  • Use Perianth: The checkbox shows whether or not perianth characters are used for classification.

The data cannot be changed on this page. A doubleclick on a record opens the input page where the data can be edited.

 The buttons in the upper panel have the following functions:


  • Open: opens an existing database.

  • New: creates a new and empty database.


  • Record: deletes the current record.

  • Classifications: deletes all classifications (the entries in the field 'Weight ...'. All other data remain unchanged).


  • Index: switches the index on or off (green = on, red = off). If the Index is 'on' the records are shown in alphabetic order according to the entry in the Observation-field. If the Index is 'off' the records are shown in the natural order.

  • Reindex: Creates a new index.

  Classify records

  • Current record: classifies the current record and jumps to the 'Output-Page'.

  • All records: classifies all records in the database currently in use.

  • All without sporophytes: classifies all records without using sporophyte characters even if they are available.

  • All fast: classifies all records using the fast test (see 'Fast test-Page')


3  Input

This page allows the addition of new records and the entry of modification of data.


  • add record: adds an empty record to the database.

  • save record: saves a new record or changes in an existing record.

  • cancel: cancels the changes in the current record

  • delete record: deletes the current record

  • classify record: classifies the current record and jumps to the output page.

All characters should be entered correctly in order to achieve a correct classification.

The two sporophyte characters on the red panel are not necessarily required for the classification, although the classification is somewhat more reliable when these characters are used. Genera with complicated bilobed leaves are always classified without perianth characters, even if these data are available.

If sporophyte characters are to be used the checkbox "use sporophyte characters” must be checked.


4  Fasttest page

The fasttest uses only 14 characters, all of which are normally recognizable with the hand lens. In many cases the results of this test are somewhat less reliable. Currently this fast test classifies about 94% of all records correctly.

The button functions are identical with the input page.


5  Output page

This page shows the result of the classifications. The genus with the highest weight (the most likely classification) is shown on the blue panel, the genera with lower probability are shown below. The highest possible weight for a classification is 1,00.

On the right part of this page a list of European species of the genus with the highest classification is shown. Clicking on the other genera on the left side will show the corresponding information.

The button “Show Image” shows an image of the genus in the image window (if an image is already available). Currently there are images of only 6 genera included (Porella, …..)

The button “Web image search” will open the standard web browser and initiate a picture search with Google. This feature can be adapted to any other internet search engine of your choice (Altavista, AllTheWeb, …) by changing the search string in the “Options window”.


The Options Window

Start Database: With this option you can change which database is opened when the program is started up. If the edit is empty, the default database will be opened.

Web search string: With this option you can adapt the internet picture search to any search engine. Perform a search of a genus with the search engine of your choice. Copy the part of the URL in front of the genus in the edit. For example in the case of Google:

URL: http://images.google.de/images?q=Frullania&ie=UTF-8&oe=UTF-8&hl=de

Search string: http://images.google.de/images?q=

Language: Select the language at program start-up (German or English)


Look for update: Looks if a newer version of Bryobrain is available. Requires an active internet connection! This function only reads data from the Bryobrain homepage. No data from your system will be transmitted.


The Image Window

The Image Window shows pictures about genera and characters (if available).


The Help Window

Shows information about the program.
