Dear AMBER users
(1) I am working with the AMBER tutorials titled " Ligand Binding using MM and QMMM techniques." available at http://www.rosswalker.co.uk/tutorials/psc_workshop/contents.htm. 
(2) Though the tutorial recommends, AMBER 9 , I am working with AMBER 10. assuming that this exercise should also work for AMBER 10 as it is an updated version

(3) While I could complete few of the initial steps; i.e, using tleap for protein, I have got error when I executed similar type of command for ligand

(4) The error is pasted below:
----------------------------------------------------------------------------------------------------------
[root_at_server exe]# ./tleap -f taz_setup.leapcmd
+ /usr/local/amber10/bin/teLeap -I/usr/local/amber10/dat/leap/prep -I/usr/local/amber10/dat/leap/lib -I/usr/local/amber10/dat/leap/parm -I/usr/local/amber10/dat/leap/cmd -f taz_setup.leapcmd

(6) I tried with xleap also, but ended with the same type of error

(5) I request you to guide me in solving this error. Should I use only AMBER 9 for this type of exercise or can I use AMBER 10. Please suggest any other alternative
