Help on Pictures
You are on the Picture's level
You are one level below the system's level. There is no level below.
Contents of this Document
Each page on this server looks like this help page. See also the
sample page. A button bar is
installed for quick references as well as search and help support. It consists of a
list of clickable symbols (buttons) which perfom several actions. See the
Symbols and Buttons section of this document
for more information. In the help page all buttons of the button bar are present
but some of them perform the same action or are references to the help page itself.
Long documents have a Table of Contents with references to the sections
of the document. You can use this clickable references or you use the pull up
and pull down feature of your browser. (It depends on your browser and
net facilities which way is the best for you.)
The content of the document can be divided into several sections which are
given in the Table of Contents. Short documents do not have sections. It's also
likely that Home Pages have no sections because they do not really support you
with low level information and are only for better navigation. If you want to
know more about the hierarchy of the documents, Home Pages, levels etc.
see the Navigation Section in this
There are some special sections in the documents:
Here is a list of symbols and buttons used at this server:
- The Link Section: In this section important links to
related documents on this server and to others round the world are listed.
- The Return Section: In this section important links are given for your navigation
on this server. It depends on the hierarchy and the contents of the page which return
options you have. Possible returns are to several Home Pages (the Server's Home, the
document's home) or other documents (previous page and next page etc.).
- The Search Section: In this section you can perform your search if this option
is activ in the document. For more details see the How to perform a search
section in this document.

If these symbols are clickable (buttons) they give you a link!
The hierarchy of the documents is built up like a directory tree. The highest level is the
root level of the server (Server's Home Page). On this server are several server levels
depending on your entry point. The system's home is the highest level (entry point for
local users). Next level is "the WWW-Raman-Server's" home (the general entry point).
In the corresponding Help Page your actual level is displayed below the button bar. To
each level a home page exists which is called document's home page for all the
documents on the same level. For the symbols used for the several home pages see the
Symbols and Buttons section.
Hypertext enables the possibility to make references to other documents independent of
any hierarchy. Therefore, you have not to care about the actual hierarchy if you are not
performing a search. See the How to perform a Search section
for more details. Links independent of hierarchy are established anywhere in the document
by clickable words or symbols in the text, in the Link or Return section or
at the button bar.
Two special links are the "previous page" and the "next page" which give
a logical chain of documents. At home pages these links can move you up and down the levels.
In documents you can go forward or backward the logical chain.
A search utility has been installed on this server. The search does not use keywords of the
documents but searches specific files for specific strings. This search method has the
advantage of less disk space (no keyword files) and that the user can determine any string
he wants. On the other hand this kind of search can be rather time consuming because each
search has to be performed on-line through all documents.
The search starts at the level of your actual document and does only look to files at the same or
lower level. Be careful by using the search utility by looking for strings in files. If you do
this at high document's level (e.g. system's home) and you have not appropriately restricted
your filenames you will run out of time. If you want to find information which you think is
characterized by the occurance of a specific string like 'abc' you should perform first a
search for the Home pages of documents containing such a string. If 'ABCD' is a SUBJECT
name for your keyword start your search first at high level with the two keywords: index.html 'ABCD'.
The result of this search will give you all Home Pages (index.html) with the subject 'ABCD'.
In the next step go to one of these Home Pages (you can click the search result) and search
for document files (*.html) containing string 'abc'.
For your search you can give two keywords: 1. the filename; 2. the search string. You can also
give only the filename if you only want to search for specific files (fastest method). For filenames
you can use wildcards as usual in unix.
In this Section additional links of the document are given.
The returns of the document are given in this section. The symbols as defined in the
Symbols and Buttons section are used. Not all return buttons are activ in any document. In the
help page all possible returns on this server are listed but not all are activ.
Return to System's Home Page
Return to the WWW-Raman Server
Return to Document's Home (the same as System's home)
Goto previous page (the same as System's home)
Goto Next Page (not activ)
Goto Help Page (not activ)
Here you can search for specific files public on this WWW-Server and lower in hierarchy than this document.
Please consider that the time of your search depends how many files have to be looked through.
It is much faster to look only for filenames than for strings in the files. Make the search as specific as
possible to avoid stupid things as searching for strings in *.gif files.
- Enter the filename you are searching for as the first keyword. (Wildcards as *.html allowed)
- The second parameter can specify the search for a specific string in that file. (optional)
