[Wien] 2 problems with w2web

[pieper]

I encountered two minor problems with w2web of Wien2k 17.1 (I am no good 
around perl so my analysis is probably poor or simply wrong):

1) The default call of the save_lapw script from the 'Utils' menue lists 
(and saves) only
"qtl*, elnes, innes, inq, inb, broadspec, klist and kgen files saved 
under ./Co-hcp-test".

This probably is the second last of the alternative options one can 
check in w2web's 'save_lapw' menue. I  was unable to call the default 
behaviour since there is no box to check for this.

I guess this is w2web working on a wrong default, the save_lapw command 
from terminal works as advertised.

I noticed this only when I updated my Linux (now OpenSuSe Leap 42.2) and 
simultaneously Wien2k (now Wien2k 17.1). So the problem might be 
connected with my new perl version (perl 5, version 18, subversion 2 
(v5.18.2)).



2) The plot feature of w2web's scf analysis script crashes when 
structural relaxation is active and HFFnnn's are selected for the plot.

Probable reason (I ran into this when writing a python script for 
analysis)): It appears that in scf cycles with structural relaxation 
active the HFFnnn labels are printed (perhaps HFF's are only 
calculated?) to case.scf only during the finalizing iterations. This 
makes the number of iterations larger than the number of HFFnnn values. 
Maybe the module filling in the plot arrays is confused by this.

Best regards,

Martin Pieper
