The interface to Abinit (updated to the latest production version) is available.
The a2y interface reads the KSS Abinit file that is normally generated prior to a GW calculation. More informations about how to generate the KSS file can be found here.
% a2y -F KSS_file
| -N | force a2y to run in sequential mode. |
| -F <opt> | Specify the name/prefix of the KSS file name. |
| -N | Skip MPI initialization |
| -O <opt> | Output directory |
| -S | DataBases fragmentation |
| -a |
Lattice constants rescaling factor |
| -t | Force no TR symmetry |
| -y | Force no symmetries |
| -w | Force no wavefunctions |
Note that, if your KSS file name is C2h3_surf.KSS you can either use
a2y -F C2h3_surf.KSSor
a2y -F C2h3_surf
