In a previous post, I discussed the sequence read format (SRF), the implementation of the SRF specification for Illumina/Solexa data, and potential implementations for Roche/454 and AB SOLiD data. Well, the potential AB SOLiD implementation has become an actual implementation with the release of solid2srf version 0.6.6. The software is released under the Applied Biosystems SOLiD™ Tools Software License (Unsupported) license [pdf], which appears to be an open source license. Quoting from the license:

You may reproduce and distribute copies of the Software or derivative works thereof in any medium, with or without modifications, and in source or object form. You may add your own copyright statement to your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of your modifications, or for any such derivative works as a whole, provided your use, reproduction, and distribution of the Software otherwise complies with the conditions stated in this Agreement.

Despite the open source license, you do have to register on their GForge site to download the software.
