greetings, a friendly reminder: please remember to subscribe before posting to the molvis list. if you do not subscribe, your posting is at the mercy of the list administrator. practically speaking, this means that I may reject or delay your message if I don't have time to verify that its contents are relevant. (note: the large majority of posts from non-subscribers are rejected immediately, to free you all of UCE.) subscribing helps us administrate the list more efficiently, and it helps us validate the list's existence as well. it is free, and somewhat painless, and can be done from this url: <https:// bioinformatics.org/mailman/listinfo/molvis-list>. if you can not recall whether your email address is on the subscription list, please send me an email (off-list, please!) from the account in question, and I will be happy to look for you. thanks for your patience. happy visualizing! tim -- Timothy Driscoll em: molvisions at mac.com molvisions - see. grasp. learn. ph: 919-368-2667 <http://www.molvisions.com/> im: molvisions usa:virginia:blacksburg tx: molvisions at vtext.com "All I've got now is a long time, and a slow, slow burn."
