<div> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br>hi all </div>
<div>when i am about to compute dynamt.x ,there is a error(see below)</div>
<div>i know someone has met the same problem ,but his solution is :go back to scf ,and specify the ibra ,and then compute form the scratch. </div>
<div>i want to know why i must to specify the ibra ,once i use a very strange cell,especially iwheni use supercell.and not belong to any of the bra ? how to slove the error?</div>
<div>i wish get your help .</div>
