ncbi-tools6 (6.1.20170106+dfsg1-0+deb10u2) buster; urgency=medium As of version 6.1.20170106+dfsg1-1 (and corresponding -0+deb* stable updates), Debian no longer distributes the full UniVec database because it contains some non-free sequences. (Invitrogen Corporation holds copyright on them and requires a license for commercial use.) The UniVec_Core database remains available for explicit use, for instance by passing -d /usr/share/ncbi/data/UniVec_Core to vecscreen. Also, any user for whom this legal restriction isn't a concern can download and use a copy of the UniVec database from https://ftp.ncbi.nlm.nih.gov/entrez/misc/data/. Apologies for any resulting inconvenience. -- Aaron M. Ucko Sun, 25 Aug 2019 21:15:11 -0400
