We've found a bug in the 1997.0 and 1997.0.1 Staden Package versions. This bug is trivial to fix and will be fixed in tapes sent out after the 7th May. The distribution is now numbered 1997.0.2.
The interaction between Pregap (in interactive quality clip mode) and Trev is broken so the actions of using Exit and Reject in trev to accept and fail readings are reversed. This does not cause problems for non interactive quality clipping.
The fixed file, trevrc, should be placed in the $STADENROOT/tables/ directory. It can be ftped from the following location:
ftp://ftp.mrc-lmb.cam.ac.uk/pub/staden/trev/trevrc
... or uudecoded from the following text. (The file contains some long lines so uudecode is used to avoid problems with some software.)
