Notes on how this package can be tested.
────────────────────────────────────────

This package can be tested by executing

    sh installation-test

in order to confirm its integrity.

To test manually, cd to some dir where you have write permissions
and do

    cp -a /usr/share/doc/concavity/examples/* .
    gunzip 1G6C.pdb.gz conservation_data/*.gz
    ln -s 1G6C_A_jsd.scores conservation_data/1G6C_C_jsd.scores
    ln -s 1G6C_B_jsd.scores conservation_data/1G6C_D_jsd.scores
    concavity -conservation conservation_data/1G6C 1G6C.pdb test1

In this call 1G6C.pdb can be replaced by other PDB-file, for example, 
taken from RCSB PDB database [1]. 
Meaning of `-conservation` optional parameter and other available optional 
parameters are explicitly described in this package's README.txt.

Note, that second positional argument ('test1' in above example) must be output 
suffix for naming resulting files. Providing path instead of suffix like in 
this call: 

    concavity 1G6C.pdb examples/test1

- produces error (it is normal behavior):

  GAPS ERROR: No such file or directory
  Unable to open file 1G6C_examples/test1.dx

Output is always saved to current folder. Make sure to cd to correct working 
directory before running concavity!

Note that PyMol script produced by concavity (.pml file) is not tested by this 
testsuite. If you want to run this script from different harddrive/other PC, 
make sure to copy also .pdb and .dx files produced by concavity, and save them 
to the same folder where .pml file will be located.
