band structure


Clicked A Few Times
Dear All:

Is the pnma space group a simple orthorhombic lattice ?

Because an error occurred after running the following input file.

I appreciate any help.

Input errors
I see input errors, such as

beta= 90.d0 should be beta 90.0d0


ngrid: 24 24 24 and ewald_ncut: 4 should loose the ":"

Dear Bert;

Please note that after correcting the errors in the input file I got the same output error.

Band Structure output file format
Are there any resources I could use to learn about the format of this file? I can infer the special k-point locations once it's plotted but it would be nice to see how the horizontal axis is scaled. I didn't see this detail in the source code "band" module, but I could have missed it.
