Does anyone know of an FTP site where I can get the ESPA (extended sib-pair analysis) program developed by Sandkuyl (sp?)? Barring that, could anyone supply me with Dr. Sandkuyl's EMAIL address (Delft, Netherlands)? Thanks, Don Bowden Dept. of Biochemistry Bowman Gray School of Medicine bowden at mgrp.bgsm.wfu.edu
