2.0 (2002) [GEC, GH, JMC, SEB]
This second version of WebLogo is a complete rewrite of both
the user interface and the backend. Many new features and
options have been provided.
1.0 (1995) [SEB]
The original version of WebLogo was written in 1995 by Steven
Brenner, and was hosted by the School of Biological Science,
University of Cambridge
Installation
After unpacking the tarfile, it should be possible to immediately create
logos using the seqlogo command line client.
./seqlogo -f globin.fasta > globin.eps
WebLogo requires a recent version of gs (ghostscript)
to create PNG and PDF output, and
ImageMagic's convert to create GIFs.
./seqlogo -F PDF -f globin.fasta > globin.pdf
./seqlogo -F PNG -f globin.fasta > globin.png
./seqlogo -F GIF -f globin.fasta > globin.png
To use WebLogo as a web application, place the WebLogo directory
somewhere within the document root of your webserver. Your webserver
must be able to execute logo.cgi (seqlogo is the command line interface,
logo.cgi is the web interface) and read/write to the cache directory.
Copy the file logo.conf.init to logo.conf, and edit the paths found
within so that logo.cgi can find gs
and convert.
Apache: In the httpd.conf file, you may have to add an ExecCGI
option to the weblogo directory, and add a cgi handler.
Something like...
Options FollowSymLinks MultiViews ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AddHandler cgi-script .cgi
Known Bugs:
* Some installation problems can cause WebLogo to fail without returning
any useful error message. Please double check the installation directions.
* GIF and PNG logos cannot be saved correctly in IE for windows.
The logos display correctly, but when you try to save them the only file
type option is BMP! One workaround is to copy the image url into another
IE window and reload the image. IE will then allow you to save the file
with the correct filetype. Other workarounds are to use a different web
browser, or a different OS (Or both).
* The "I" charachers representing isoleucine residues aren't easily
identifiable as "I" charachers in the WebLogo font.
* The Outline Characters option turns off antialiasing.
* Frequency plots will not show the y-axis scale or label.
