CPIN seems fine. Could you please send me your CPOUT file as well so I can attempt to reproduce your issue locally?

Subject: [AMBER] Cphstats unable to read cpin

Dear Amber Community,

Iím running constant pH simulations with a large number (~100) titratable residues. Cphstats complains that the associated cpin file canít be parsed. When I look at constants.h, I see that TITR_RES_C 200, causing me to think that the large number of residues is not the issue. Iíve attached the cpin file to this message. Iíd greatly appreciate advice on how to fix this issue.
