Hello Dulal,
Could you please try running your simulation with Amber24 and let us know if you encounter any issues? Since you’re currently using Amber18, addressing any problems might be challenging at this point since Amber18 was released several years ago. Additionally, when using Amber24, ensure you regenerate your CPIN file with cpinutils.py from Amber24.
I hope this helps!
Best regards,

Subject: [AMBER] Error to run constant pH replica exchange in explicit solvent in amber18
Dear Experts,
I run constant pH replica exchange in amber19 using pmemd.cuda.MPI. My
titratable residue is 48 (less than 50). But I get the following error
message.
At line 167 of file constantph.F90 (unit = 23, file = '004/cpin.rep.032')
Fortran runtime error: Index 1 out of range for namelist variable stateinf
In the mdout file I see the following message.
Implicit solvent radii are H(N)-modified Bondi radii (mbondi2)
|reading charge increments from file: 009/cpin.rep.032
I also upload the cpin
file.
Thanking you in advance
