Please 1) install default cygwin from http://sources.redhat.com/cygwin/ 2) run /usr/X11R6/bin/startxwin.bat to start the X server Then, copy A.exe, xterm.exe and all the .dll files to a PATH location, or, if you just want to try out the downloaded program in a temporary directory, type under bash prompt, $ PATH=$PATH:. Then, type $ DISPLAY=localhost:0; export DISPLAY Then, try $ xterm If xterm is working, then try $ A DNA.pdb Ju Li. Thu Jan 24 03:39:26 2002 ps: If you see error message 'The procedure entry point __getreent could not be located in the dynamic link library cygwin1.dll.', it means you are using an outdated c:\cygwin\bin\cygwin1.dll emulation kernel (assuming c:\cygwin is your cygwin root directory). Either update your cygwin installation by going to http://sources.redhat.com/cygwin/, or, copy the provided DLL file 'Kernel/cygwin1.dll' in the unzipped folder to c:\cygwin\bin\ (cannot do this in cygwin terminal - must do it in Windows - and a good idea is to save the old kernel first by renaming it cygwin1.dll.old).

The xterm.exe included in this directory is ver. 196, which works well. Ju Li.
