Hello everybody, I am a very inexperienced new user of Linux / cygwin and having problems in installing DMS and Chimera: 1. I am trying to install DMS but having problems with specifying correctly the pathway to the appropriate locations of the BINDIR and LIBDIR directories in the GNUmakefile. I am getting a message: "Cannot create directory. not such file or directory". I have tried it both on Linux enterprise 4 and on Windows using cygwin. My pathway includes spaces, i.e: /cygdrive/c/Documents and Settings/User Name/Desktop/dms/bin Can anyone please tell me how exactly I should enter the pathway (I think the spaces cause the problem but not sure)? 2. I am having problems running the chimera-installer.exe. file of Chimera on Linux. When I double-clicked on it, it tells me that I cannot execute the file, so as suggested in the instructions (http://www.cgl.ucsf.edu/chimera/1.2304/linux.html) I typed chmod +x 'filename' . When I checked the properties of the file after chmod, the box of 'execute' was checked (so I believe that I really changed the file's permissions). However, I am still getting the same error message when I double-click it. Does anyone know what am I doing wrong? Please consider my lack of experience in UNIX terminology if you try to answer one of my questions, Thanks a lot, Ben
