Dear Volodya,
I cannot immediately see anything wrong with your input file but sometimes
email formatting can hide underlying formatting errors. The error message
also does not make it clear what unit number the read error occured on. Thus
it could be a read error with the prmtop or inpcrd file. Could you please
post me (as attachments) your inpcrd, prmtop and input files and I'll try it
out on my machine and see if I can see what is wrong. Also, what version of
Amber are you using?
All the best

    ntb=2, ntc=2, ntf=2, nsnb=25,

Unfortunatly, It doesn't work. I have in log file next:

What can you reccomend me?
