[AMBER] Problem with QMMM with Amber/Gaussian interface.

Dear All,

I am having a problem when trying to run QM/MM calculations with Gaussian09 as the external program.

I keep getting this error:

"SANDER BOMB in subroutine qm2_extern_get_qm_forces
 External namelist not found
 Please check your input.”

But the problem is that I do have the external namelist in my input file!
Here’s my input file:

——


QMMM Test

&cntrl
  imin=1,
  ntx=1,
  irest=0,
  maxcyc=100, ncyc=50,
  cut=8.0,
  ifqnt=1
 /
 
&qmmm
iqmatoms=863,864,865,866,867,868,869,870,871,872,873,891,892,893,894,895,896,897,898,899,1508,1509,1510,1511,1512,1513,1514,1515,1516,1517,1518,1846,1847,1848,1849,1850,1851,1852,1853,1854,1855,1856,1857,1858,1859,1860,1865,1866,1867,
  qmcharge=-1,
  spin=5
  qm_theory=‘EXTERN’,
 /

&gau
  method = ’B3LYP’,
  basis = ’6-31+G*’,
  num_threads = 16,
  mem=’2GB’,
 /

Does anyone have an idea how to fix this issue?

Thanks a lot!
Sadra
