script for bandgap

[rvgr]

i have edit script for band gap but its doesn't show any result.
i upload script

[Umberto Martinez]

that is beacuse you do not save anything.
Not sure how you created that file but you miss a line like:
nlsave("analysis.nc", bandgap)

not that "your" bandgap is actually the bandstructure analysis.
you calculate the band gap FROM the bandstructure

i don't get point where i am wrong, pls help me to find out band gap.

now you do not print anything. your script should be something like:

Code

...
nlsave('C:/Users/Lenovo/.vnl/example_project_2014.0/zigzag.nc', bandstructure)
#bandgap
ind_gap = bandstructure._indirectBandGap() .inUnitsOf(eV) 
print ind_gap

Note that you can calculate the gap form the bandstructure even though you have already run the analysis. In that case run:

Code

bandstructure = nlread("zigzag.nc", Bandstructure)[-1]
#bandgap
ind_gap = bandstructure._indirectBandGap() .inUnitsOf(eV) 
print ind_gap

cf. nlread, nlsave and bandstructure entries in the Reference Manual
