Hi,
Thanks very for Ray and Alessandro's advice!
I try Alessandro's advice and add the following line to $AMBERHOME/src/mm_pbsa/mm_pbsa_createinput.pm to 435 lines:
print OUT " fillratio=3 \n";
However, a new problem comes out:
The output file shows:
"---
WARNING: Missing PB for PB in 0 -> Taken from -1
WARNING: Missing PB for PB in 1 -> Taken from 0
WARNING: Missing PB for PB in 2 -> Taken from 1
---
Calc delta from raw data"
Also the command lines shows:
" ---
Use of uninitialized value in multiplication (*) at /usr/local/amber9/src/mm_pbsa/mm_pbsa_statistics.pm line 1336.
Use of uninitialized value in multiplication (*) at /usr/local/amber9/src/mm_pbsa/mm_pbsa_statistics.pm line 1336.
No data for 0+2 PB PB 0"
The new problem is same as that I change "SCALE" 2.0 to 3.0. But this time SCALE is 2.0
I search past posts and cannot get results.
Moreover, Ray, can u explain to me more details about how to add fillratio to 3.0? Which file I should correct in $AMBERHOME/src/mm_pbsa?
I read previous emails about this and cannot get detailed answers.
Thanks very much for your help,
