Dear all,

Thanks all for your helpful comments. I've installed the tcsh package in
Cygwin. However, I've encountered another problem. When I try to run xleap
by typing "$AMBERHOME/exe/xleap -s -f $AMBERHOME/dat/leap/cmd/leaprc.ff99SB"
I just end up getting the following message:

"/cygdrive/h/amber9/exe/xaLeap: /cygdrive/h/amber9/exe/xaLeap: cannot
execute binary file"

I've also tried the following:
$ xleap
/cygdrive/h/amber9/exe/xaLeap: /cygdrive/h/amber9/exe/xaLeap: cannot execute
binary file

$ xaLeap
./xaLeap: ./xaLeap: cannot execute binary file

I wondered whether it was a permissions problem, so I tried:
$ ls -ll xaLeap
-rwx------+ 1 Lili None 3467265 Mar 29 15:54 xaLeap

...Obviously I have read, write, and execute access, so it can't be a
permissions issue..

Does anyone have insights on the problem?

Thanks,
Lili
