Francesco -
Okay, this is purely a matter of nonprinting characters in the mdin file for
the MD RUN. Unfortunately, Ross and I were misled by the mdin,
"vac_min.in", which was for the minimization, and which was the only mdin
sent in the group of files to the list. SO I looked at the output of
eqmecycl_vac_md1_12Acut.out. This is the output that produces the "Could
not find cntrl namelist" message. If you look at the echo of the mdin
input, it looks fine here, and it is also clear we were looking at the wrong
mdin. However, if you do an "od -c eqmecycl_vac_md1_12Acut.out > od.dmp"
and look at od.dmp, you will see, with a little work, that there are two
nonprinting characters, octal 302 followed by octal 240, in front of every
mdin input line. Perhaps the mdin file was made on another operating
system, with a different native language, or some such? You need to use an
editor like vi on a compatible unix system, or edit the current one, getting
rid of the apparent blanks, which I would guess are some sort of unicode and
replacing them with true blanks. Then run the mdin you created through
od -c again, confirming that all the nonprinting characters that previously
showed up as octal numbers have disappeared. Most likely, this is all that
is going on. For my edification, I would be interested to know how you
generated this file; I have had trouble myself moving files from windows to
linux, but I think that was a matter of /r/n instead of /n at the end of the
lines (windows has a different line termination convention than unix). Have
fun with the dogs; if you fix the mdin, you really should be running.
Best Regards - Bob
