|
|
|
3 logos from biological sequence alignments. It can be run on the command line,
|
|
|
4 as a standalone webserver or as a CGI webapp.

27 There is a known issue with GPL Ghostscript 9.04 which affects some users which may cause ghostscript to segfault.
|
|
|
28 This is not believed to be a problem with CodonLogo.
|
|
|
29 This is being investigated. if you encounter this problem it's recommended to downgrade to version 9.01 or earlier of ghostscript.
