Hi Arkinyemi,

The update.3 of AmberTools21 is about changing the leaprc.water.opc, leaprc.water.fb3, and leaprc.water.fb4 files to load the recently published ion parameters for the OPC, TIP3P-FB, and TIP4P-FB water models, respectively.

If you did not apply the update.3 of AmberTools21 when installed AmberTools21, attached are the three updated leaprc files which you can use to overwrite the corresponding old files in the AMBER source code directory and AMBER installation directory.
