Hi Elvis,
I do have the radiopt=0 in the input. Please see below:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
MM-PBSA with original PB solvation model (inp=1)
&general
startframe=7002, interval=5, endframe=7500, verbose=2, keep_files=1,
debug_printlevel=2,
/
&pb
istrng=0.15, inp=1, cavity_offset=0.92, cavity_surften=0.00542,radiopt=0
/
&decomp
idecomp=1, dec_verbose=3
/
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I tried increasing the memory being allocated to each cpu... this time it
seems finished. But the final results file they are huge positive numbers,
it also reminded that "WARNING: INCONSISTENCIES EXIST WITHIN INTERNAL
POTENTIAL
TERMS. THE VALIDITY OF THESE RESULTS ARE HIGHLY QUESTIONABLE"
I am wondering is there something I need to change for default to get
correct results?
In one of the mdout temporary file, there is such a line:
| Flags:
PB Warning in pb_read(): sprob=0.557 is optimized for inp=2 and should
not be used with inp=1. It has been reset to 1.4.
The program changed sprob for me. But other than that, I don't know where
other warnings are...
Thanks!
Guqin
