Recently, I used mp2 level to calculate qmmm, but nwchem could not run. And who can help me to solve this problem?
The error informations are as follows:
NWChem Property Module
----------------------
------------------------------------------------------------------------
util_file_name_resolve: filename too small 257
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
44: task qmmm mp2 optimize
------------------------------------------------------------------------
------------------------------------------------------------------------
There is an error in the input file
------------------------------------------------------------------------
For more information see the NWChem manual at
