Dear CPMD-list:

I tested for generating coordinates using point group and got some error
messages. Below please have a look at the input and output:

>>>>> INPUT <<<<<
&CPMD
  OPTIMIZE WAVEFUNCTION

&SYSTEM

 GENERATE ATOMIC COORDINATES FROM SYMMETRY UNIQUE ONES
 GENTAU| INCONSISTENCY FOR SPECIES:                             1
 GENTAU| NUMBER OF ATOMS:                             5 NOT     2


The results look fine when the oxygen entry was deleted--The resultant H
coordinates are (0.5, 0, 0) and (-0.5, 0, 0) instead of the input (0.5, 0,
0) and (1.5, 0, 0).  Could somebody tell me what's wrong when the oxygen
atom was included?

Thanks in advance!
