Ian:

Thank you for responding at 22:00 on a Friday evening.

Your suggestion of using ./my_radii.lib led to the program recognizing the file.

CCP4 should considering modifying the sc.doc document to make the fact that the 
directory needs to be specified explicit.

Hi Steven

SCRADII is defined in $CINCL/defaults.def which if I recall correctly implies 
that by default it will look in $CLIBD for the file, unless you specify a 
directory explicitly.

So you could try:

% sc XYZIN foo.pdb SCRADII ./my_radii.lib

Hope it works!

Cheers

All:

We are running CCP4 v6.1.3.  I have recently tried to use the Program SC, which 
calculates Surface Complementarity of an interface between two components.  I 
can get it to run fine, but I have one complex, where one of the partners has 
carbohydrate residues, which have atoms that are not part of the standard 
library, sc_radii.lib.  The sc.doc file notes that one can use one's own atomic 
radii library by adding the keyword, SCRADII to the command line, i.e.

% sc XYZIN foo.pdb SCRADII my_radii.lib

However, the log file shows that SC is continuing to use $CLIBD/sc_radii.lib, 
rather than the library I have tried to provide.


*         Has anyone had any recent experience using SC with using their own 
radii library?

o   If so, how did you make it work?

*         Is it possible that this program is used so rarely that the mechanism 
for using one's own radii library was accidentally broken and no one noticed?

Steven
