These programs are an implementation of the PRN method (Lecointre et al., 1994, Mol. Phyl. Evol., 3:292-309) and have been used in some works now (Philippe et al., 1994, Development, Supplement: 15-25; Philippe and Douzery, 1994, J. Mamm. Evol. 2:133-152; Carranza et al., 1997, Mol. Biol. Evol. 14(5):485-497; Steiner and Muller, 1996, J. Mol. Evol. 43:58-70).

They are written in ANSI C for UNIX Systems and are distributed in a tarred format of approximately 270 Ko. Once untarred (tar -xvf prnmet.tar), you will find the sources and a brief manual in a directory called prn. You will then have to compile the sources, using the standard UNIX compiler or any C compiler you like.

These programs have been written by H. Philippe. If you encounter any problem with them, you should send him a  mail .
