'Morning to everybody!
I have some trouble about the postprocessing in pp.x, and maybe some of
you could give me some nice idea about:
I use to calculate |PSI|2 for some of the state(of interest!) of my
system, so HOMO, HOMO-1, LUMO etc...
with pp.x
and next to plot them again with pp.x in order to achieve the right
input format for Xcrysden.
I do this for each separate state I calculate with pp.x (here the input
file, that works!..):
first step (pp.x @ pw_3.2)
&inputpp
prefix = 'scf'
outdir = '${DIR_SCRATCH}'
filplot= '${DIR_SCRATCH}PSI2.0${STATE}'
plot_num=7
kpoint = 1
kband = ${STATE}
/
STATE = number of orbital I want to plot....
next plot part:
&inputpp
/
&plot
nfile=1 ,
filepp(1)='PSI2.0${STATE}' ,
weight(1)=1.0 ,
iflag=3 ,
output_format=5 ,
x0= 0.0 0.0 0.0 ,
fileout='./PSI2_0${STATE}.xsf'
/
finally my question:
instead having for each state one corresponding file.xf ("HOMO.xsf" and
"LUMO.xsf" for example) and to plot HOMO and LUMO separately for the
same system with Xcrysden, is there the possibility to obtain only one
file.xsf in order to plot the HOMO and LUMO on the same structure with
Xcrysden??
Have I been too unclear?
Nevertheless, thanks in advance!
cheers!
