Hi, the periodic box is about:
22000 76.154 0 0 0 74.2013 0 0 0 79.083 25.5 37 23.3 -3.78574e-06-3.78574e-06 -3.78574e-06 0 0 0
at 22000 step, which is the starting for the next MD run. And I setthe cell basis vectors as:
cellBasisVector1 78.00 00.00 00.00cellBasisVector2 00.00 76.00 00.00cellBasisVector3 00.00 00.00 81.00cellOrigin 25.5 37.0 23.3
margin 5
Pme onPmeGridsizeX 78PmeGridsizeY 76PmeGridsizeZ 81
Thank you for any suggestions.
Bo
