   David,
   I recently (April) installed amber14 tools from AmberTools14.tar.bz2
   and I do not see
leaprc.parmbsc0_chiOL4_ezOL1

in my cmd directory

   Did this require an update beyond whatever autoupdate is activated during
   the install process?
   If memory serves me, the amber14.pdf says this file will be forthcoming so I
   downloaded the supplemental material from the original publication.

Hi all,I have seen you sent the force field (ff99 + bsc0 + ε/ζOL1+
χOL4) for DNA. I want to use the latest modified force field to
computate the DNA. Could you give me the nearest modified force
field(ff99 + bsc0 + ε/ζOL1+ χOL4) for DNA?

Please use leaprc.parmbsc0_chiOL4_ezOL1, which is in AMBERHOME/dat/leap/cmd
in the AmberTools15 distribution.
