Frequently asked questions about Clustal licensing?
---------------------------------------------------

1. Do I have to pay to use ClustalW or ClustalX?
No - unless you wish to redistribute Clustal for profit. In this case see question 4.

2. Can I redistribute the Clustal binaries and source code?
Yes. We have always wanted to see Clustal have as wide a userbase and distribution network as possible and are happy to see other sites host copies of the official Clustal code.

3. Can I make changes to the source code?
You can make changes for your own purposes but you should not redistribute the changed code.

4. I want to include ClustalW/ClustalX in a commercial application who should I contact?
Toby Gibson at gibson@embl.de (also cc des.higgins@ucd.ie)

5. There is no Clustal distribution for platform X. I have changed the code in order to compile Clustal on this platform. Can I redistribute it?
Ideally you should send us a copy of your source code changes as well as a binary. We will include it in our contributed binaries section on our FTP site along with an acknowledgement of your contribution.
