Dear Armin,
the parameters, prepfiles etc. for the lanthanides (and related calixarene ones)
were used with an older Amber version (v4.1). I just checked, and they still do
work with my older amber executables, but require the prep-link-edit-parm
sequence that was used at the time.
Unfortunately I am not certain about how you would need to go about converting
them to the current Amber 8 format, or whether there are some specific options
for backwards-compatibility built into Leap.
But in any case I think you brought up an interesting question: what should
one do to keep previous work still usable with current amber versions ? Are
there any guidelines about how to convert not only topologies but also input
files. Maybe some of the Amber developers could give us some precious hints ?
Thanks in advance,
Marc Baaden
