Dear Sir...
for plotting band structure for such structure you can first calculate band
structure at such special points (we call them high symmetry points).
for your specific points please refer to this useful website:
http://www.cryst.ehu.es/
in space group table click on KVEC and then enter the number of your structure
for example 225 for FCC OR 221 FOR bcc...PEROVISKE I don't know?.
