Thanks Ben, Yes, I am acutely aware that our interface has got out-of-date.
I can add in these little fixes. If there is sufficient interest, we could talk about updating to the python version.

I am not especially familiar with ccp4i, but I am the lead developer for Modeller, so can hopefully say something useful about that. ;) True, the latest version of Modeller is 9v2, which is very different from 6v2. However, if you are using 'old style' TOP scripts (which ccp4i generates) then 9v2 will quite happily work with the same scripts that work in 6v2. I just tried this out with ccp4i (6.0.2) using the 'simple' modeling example from the Modeller distribution (alignment.ali from examples/automodel/). For the configure window for CCP4i, I just filled in MODINSTALL to the same value as when I installed Modeller, left the install key blank (not needed for 9v2) and filled in the program name as 'bin/mod9v2'. (The bin prefix is needed because CCP4i looks in the MODINSTALL directory for the 9v2 script, not in the bin subdirectory which is where it lives in Modeller 7 and later.) To actually run Modeller, I put alignment.ali and pdb5fd1.ent in my CCP4i project directory, pulled up the 'run Modeller' CCP4i window, selected 'alignment file' for 'input sequence for structure to build as', selected 'define TOP file' (seems not to work properly without that, although I can't tell from the docs what it's supposed to do), put in 'alignment.ali' for 'Align in', left 'Top in' blank, then added two PDB files - one with code name '5fd1' and 'known in' 'pdb5fd1.ent', and another with code name '1fdx' and a blank value for 'known in'. The Run button should then run Modeller normally. This should all be fine for 'no' refinement. For the 'fast' and 'full' settings, you must edit ccp4-6.0.2/ccp4i/templates/modeller.com, and add the line 1 SET PDB_EXT = ' ' immediately after the 1 INCLUDE line. (This is because by default Modeller 7 and later write out files with a .pdb extension, while ccp4i expects them to have no extension.) The CCP4 guys may want to put this into the main CCP4 distribution, since it will also work for Modeller 6 (where it is a no-op). P.S. In at least one place in the CCP4 docs, the user is pointed to the old Modeller page at Rockefeller, which no longer exists. That link should go to http://salilab.org/modeller/ instead. P.P.S. If there is interest from CCP4 users or developers in improving the CCP4i/Modeller integration, I can certainly help out. For example, TOP scripts are deprecated in Modeller 9 in favor of Python scripts, and it would not be especially hard to change the script template to Python (although of course this would then break backwards compatibility with Modeller 4 and 6).
