BABEL is a program designed to interconvert a number of file formats currently used in molecular moldeling. The program is available for Unix (AIX, Ultrix, Sun-OS, Convex, SGI, Cray, Linux), MS-DOS, and on Macs running at least System 7.0. Babel will read the following file types : Alchemy AMBER PREP Ball and Stick Biosym .CAR Boogie Cacao Cartesian Cambridge CADPAC* CHARMm* Chem3D Cartesian 1 Chem3D Cartesian 2 CSD CSSR CSD FDAT* CSD GSTAT Free Form Fractional GAMESS Output* Gaussian Z-Matrix Gaussian Output* Hyperchem HIN* Mac Molecule Macromodel Micro World MM2 Input MM2 Ouput MM3* MMADS* MDL MOLfile* MOLIN* Mopac Cartesian Mopac Internal Mopac Output PDB ShelX Sybyl Mol* Sybyl Mol2* XYZ Babel will write the following file types : Alchemy Ball and Stick Cacao Cartesian CAChe MolStruct* Chem3D Cartesian 1 Chem3D Cartesian 2 ChemDraw Conn.

NOTE: The file formats indicated with * are not currently supported in the Mac version. We're currently working on a Mac update which will include all these formats, and few other new goodies. This update should be ready in a couple of weeks. INSTALLATION OVERVIEW Babel is avialiable via annonymous ftp from joplin.biosci.arizona.edu in pub/Babel UNIX The Unix version is in the file babel-1.04.tar.Z 1. uncompress babel-1.04.tar.Z 2. tar -xvf babel-1.04.tar 3. follow the instructions in README.1ST -------Special note for users with Sun workstations------------------- Many older Sun C compilers are not ANSI compliant and will not compile Babel. However, there are two options : 1. Use gcc 2. Download the file sun-babel.tar.Z which has a binary compiled with with gcc on a sun 4 under SunOS release 4.1.3. -------Specail note for users with SGI workstations----------------------- It seems that some people who have SGI workstations don't have a C compiler. For these people we have put an SGI binary in the file sgi-babel.tar.Z MAC The Mac version is in the file macbabel.sea.hqx 1. Use you favorite archiving program to unbinhex the archive. 2. Double click on the self extracting archive macbabel.sea 3. Follow the instructions in the file Babel Manual DOS The DOS version is in the file babel104.zip 1. pkunzip babel106.zip 2. follow the instructions in README.1ST Any questions regarding BABEL should be directed to babel@mercury.aichem.arizona.edu
