I was spending a few days reading guides and manuals for the generation of<br>
norm-conserving PPs for the calculation of the g-tensor and hyperfine<br>
splitting of EPR spectra using GIPAW module. I realized that the generation<br>
of gauge-including PPs has not been discussed at length and all the<br>
information is limited to the input guide of the ld1.x code. As I'm not an<br>
expert in PP generation, I appreciate it greatly if someone with relevant<br>
experience in making GIPAW PPs can provide an input as an example,<br>
preferably with scalar relativistic or fully relativistic forms.<br>
<br>
Thank you very much<br>
