Always a sign of problems with your CCP4 setup, yes.

Did you actually get stuck (as in: it keeps asking you for the
location of the font84.dat file)? Or did it just not work as expected?

Do you have the newly installed CCP4 8.0 version set up /before/
running the ccp4-setup tool? As in

  . /where/ever/ccp4-8.0/bin/ccp4.setup-sh        # bash/sh/zsh

    - or -

  source /where/ever/ccp4-8.0/bin/ccp4.setup-csh  # tcsh/csh


If that was the case, the ccp4-setup script should realise that you
are running a CCP4 version newer than 6.3.0 (which was the last one
using that font84.dat file) and would never ask you about it.

No.

The easiest is always to just re-install BUSTER in an environment
where CCP4 is set up (see above). Alternatively, if you update to a
new CCP4 version, just edit the file

  $BDG_home/machines/*/ccp4.setup

(where $BDG_home is the BUSTER installation directory) and change line
13 from e.g.

  CCP4="/public/xtal/ccp4-7.1"

(obviously different for you) to point to the latest CCP4
installation, e.g.

  CCP4="/public/xtal/ccp4-8.0"


Does that help?

Cheers
