Re: [AMBER] Tutorial 22 - aMD - how long should it last on Titan Black?

Hello,

I'd like to add just two words about the aMD tutorial. I haven't noticed it
before my calculations finished. I think there is a mistake in calculating
the EthreshP and alphaP value. The number of atoms in BPTI system is 17,022
not 18,226.
Could this small mistake affect in some way the calculations?

Best regards,
Karolina
