 3)I add SET BABEL_DIR=C:\BABEL to the AUTOEXEC.BAT which is in C:\Documents
 and Settings\ezw079.MATDOM\My Documents\My Received
 4)I copy the 1N5U.pdb in to C:\BABEL
 5)I entered the C:\BABEL under dos
 typed babel -ip 1N5U.pdb -ocache output.csf
 nothing happened, no error, no waring, no output.
 and I tried Open BABEL, but seems it is under Unix not DOS or Win
 Thank you in advance for your help!
