Hi CCL-ers, Does anybody know/currently write/ need a tool that converts mol-files with 3D - coordinates into mol-files with 2D - coordinates and correct stereo- chemisty, up/down bonds etc.. and the same atom numbering as the original file. A tool that could reassign original atom numbering of the 3D-file a correct 2D-file with changed order of atoms would do as well. Greetings, Maria
