[Pw_forum] Testing pseudopotential

[Padmaja Patnaik]

Dear All
I have generated fully relativistic ultr-soft pseudopotential for Cr. I am not sure of how to test it. The logarithm derivatives of all electron and pseudopotential are not exactly matching as given in the examples (examples_pseudo). below I am adding the testing portion of the output file. The value of De AE-PS is very small. Does that indicate a good generation of pseudopotential? Can anybody please mention what are the other points which should be taken care of, while testing?
