The WIEN97 package consists of several compressed tar files, which should be placed in a subdirectory which will be your $WIENROOT directory (e.g. ./lapw). Uncompress and expand all files using:
gunzip *.gz
chmod +x ./expand_lapw
./expand_lapw
Note: In case your system has no GNU zip/unzip utility installed, we can supply the WIEN97 sources also in the Unix compress (*.Z) format.
You should have gotten the following directories:
./lapw SRC SRC_averx SRC_dstart SRC_eosfit SRC_initelnes SRC_initxspec SRC_joint SRC_kgen SRC_kram SRC_lapw0 SRC_lapw1 SRC_lapw2 SRC_lapw3 SRC_lapw5 SRC_lapwso SRC_lcore SRC_lib SRC_lorentz SRC_lstart SRC_mini SRC_mixer SRC_nn SRC_optic SRC_optimize SRC_reformat SRC_spacegroup SRC_spaghetti SRC_sumpara SRC_symmetry SRC_telnes SRC_templates SRC_tetra SRC_trig SRC_txspec SRC_wienbox example_struct_files fccni tic tio2
Thus, each program has its source code (split into several files) in its own subdirectory. All programs are written in FORTRAN77 using double precision (real*8 and complex*16 !!).
/SRC contains the users guide (in form of a postscript file users_guide.ps and as an ASCII-file users_guide.asc), all c-shell scripts and some auxiliary files.
/fccni, /tic and /tio2 contain three example inputs and the respective outputs.
/example_struct_files contains a collection of various struct files, which could be of use especially for the less experienced user.
/SRC_templates contains various input templates.
In addition to the expansion of the tar-files ./expand_lapw copies also all csh-shell scripts from /SRC to the current directory and creates links for some abbreviated commands.
