Easel is an ANSI C code library developed by the Eddy/Rivas laboratory at Harvard. Easel supports our work on computational analysis of biological sequences using probabilistic models. Easel is used by HMMER, the profile hidden Markov model software that underlies several protein and DNA sequence family databases such as Pfam, and by Infernal, the profile stochastic context-free grammar software that underlies the Rfam RNA family database. Easel aims to make similar applications more robust and easier to develop, by providing a set of reusable, documented, and well-tested functions.
Easel is not (yet) released on its own. It is part of the HMMER and Infernal releases.
To participate in Easel development, visit us at github.
% git clone https://github.com/EddyRivasLab/easel % cd easel % autoconf % ./configure % make % make check
This procedure gives you our
master branch - the most recent Easel
release that was packaged with a release of HMMER, Infernal, or other
lab software. If you want a feature that we've put in more recently,
you want our
develop branch. After the
git clone and
% git checkout develop
and proceed to
