Dear Krystle,

This is pretty simple to fix, you just have to change a little of the CNS input file below the 'things below this line do not normally need to be changed' point.

In v1.2, the refine.inp looks like this:

...
{===========================================================================}
{        things below this line do not normally need to be changed          }
{===========================================================================}

) {- end block parameter definition -}

{- read define parameters if file &defaults_file exists -}
if ( &BLANK%defaults_file = false ) then
   fileexist &defaults_file end
   if ( $result = true ) then
     inline @&defaults_file
   end if
end if

checkversion 1.2

evaluate ($log_level=quiet)

{- read topology files -}
topology
   if ( &BLANK%topology_infile_1 = false ) then
     @@&topology_infile_1
   end if
   if ( &BLANK%topology_infile_2 = false ) then
     @@&topology_infile_2
   end if
   if ( &BLANK%topology_infile_3 = false ) then
     @@&topology_infile_3
   end if
   if ( &BLANK%topology_infile_4 = false ) then
     @@&topology_infile_4
   end if
   if ( &BLANK%topology_infile_5 = false ) then
     @@&topology_infile_5
   end if
end
...

If you change it to this:
...
   if ( &BLANK%topology_infile_5 = false ) then
     @@&topology_infile_5
   end if
   if ( &BLANK%topology_infile_6 = false ) then
     @@&topology_infile_6
   end if
end

...

It SHOULD work.

Yours,
Frank
