Cary,
The problem you are experiencing with XQS is due to the large size of the
GenBank and EMBL databases when each is viewed as one database. XQS, as well
as PSQ and NAQ, uses a two byte variable for storage of entry codes and
therfore can access only upto ~65000 unique entries. The display commands
will not work with large datasets.
To fix this problem temporarily we split one of the larger of thirteen from
the main set (GBPRI.SEQ or PRI.DAT) and call this supplemental dataset
GENBANKSUP or EMBLSUP. The program GB_EMBL will do this; I will E-mail a
version of this program to you. Until further notice, this protocal must be
followed for all databases with totals exceeding 65000.
