Things are heating up in the blogosphere between developers of HMMer, the freely available popular sequence analysis tool originally written by Sean Eddy of Janelia Farms. Scalability has a post pointing out some issues related to a trademark for HMMer granted to Eddy back in early April. Currently, there several open source "flavors" or "forked off" versions of HMMer, such as GPU-HMMer and mpiHMMer, that may have to be renamed or no longer distributed due to the stipulations in the trademark.
