egrad error: illegal input in <respon.f>: q < p
« on: June 13, 2008, 04:06:40 AM »
Dear all,
        In the excited state optimization process, egrad ended with error:

 illegal input in <respon.f>: q < p
error in gradient step (1)

His looks like a bug in the code. You should submit a bug report to the support desk (COSMOLogic).
