As the db grows, some entries are merged with other entries, names change, and sequences change. My codon analysis code uses a historical scheme to track data changes and such. Yes, I should probably write it to use accession numbers instead of names, but locus names me something to me (especially now that I've just about gotten the locus naming schemes figured out). If I wanted to redo an analysis from two years ago, I could not do it with the latest GB. Instead now I have created my own E. coli files from each release of GB and roll that off onto tape. That's OK for E. coli, but if I want to try primates or all mammals, that's a much bigger task. Just thought I'd mention it. dan -- dr. dan davison/dept. of biochemical and biophysical sciences/univ. of Houston/4800 Calhoun/Houston,TX 77054-5500/davison@uh.edu/DAVISON@UHOU "Mars is essentially in the same orbit...somewhat the same distance from the sun, which is very important.
