To create the hhblits libraries for a subset of structures:
Select structures from ModPipe database directory (one a3m file for each structure; get these from the hhsearch subdirectory in ~modpipe/database)
Copy to "inputdir" directory
Run: 
$HHLIB/scripts/hhblitsdb.pl -o pdb70 -ia3m inputdir -cpu 8
(Make sure the directory containing ffindex_build is in your PATH, otherwise
this won't work.)
