Dear Dr.Xavier,

Thank you for your kind suggestion.
I also calculated it using nband=28, however, the result is same.
I find a warning as following after the calculation for DATASET 2.
I don't know its meaning and is it related to my problem ?
I wish to get some further help!
Thank you very much!

transformation to cartesian coordinates may be wrong.

respfn : d/dk was computed, but no 2DTE, so no DDB output.
