All Rights Reserved Redistribution or resale, except by Semichem, Inc., is prohibited. --------------------------------------------------------------------------------------------- Learn Codessa by reading the Adobe-formatted (*.pdf) manuals in the 'docs' directory (Train.pdf, Ref.pdf and User.pdf) and using the help facilities within Codessa. Also, see the *.readme files in the 'docs' directory. To learn Codessa by example, see the 'examples' directory, which contains a small collection of sample Ampac, Mopac and Gaussian data files, Codessa "Project" (.cod) files (to be opened and saved by Codessa using "File->Open" and "File->Save"), Codessa "Input" (.inp) files (to be opened by Codessa using "Data->Load" or "Data->Auto Load") and list (.lst) files (to be opened by Codessa using "Data->Auto Load"). On WINDOWS, the batch files runampac.bat, rungaussian.bat and runmopac.bat should be edited according to the current system. These batch files are called by predict.exe and makeinp.exe to automatically run Ampac, Gaussian or Mopac, if requested or necessary. Note that the keyword "CODESSA" can be used with AMPAC jobs to produce the maximal useable information by the Codessa program. Thank You for using CODESSA 2.7.16 Semichem Contact Info: Phone: (913) 268-3271 E-Mail: support@semichem.com Web: www.semichem.com --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- Codessa requires that a valid key file, named codessa.key, be placed in the Codessa-2.7.16 directory. If you don't already have a key file for Codessa, please contact Semichem, Inc. --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- To Launch Codessa on WINDOWS use the "Start Menu->Codessa-2.7.16->Codessa icon or the desktop Codessa icon or launch the Codessa.exe file directly from the Codessa-2.7.16 folder. --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- To use Codessa on UNIX systems, the file Codessa-2.7.16/init_codessa.sh (for Bourne or BASH users) or Codessa-2.7.16/init_codessa.csh (for CSH users) must first be "sourced." This is most easily achieved by entering the following command (substitute the parent directory path of Codessa-2.7.16 for /usr/local) in your $HOME/.bash_profile or $HOME/.profile files (for Bourne or BASH users): . /usr/local/Codessa-2.7.16/init_codessa.sh or by entering the following command in your $HOME/.login file (for CSH users): source /usr/local/Codessa-2.7.16/init_codessa.csh This will make Codessa automatically available whenever you login. These commands can also be entered on the command-line of a shell window, but Codessa will then only be available for that shell environment. To launch Codessa, enter the "codessa" command (without the quotes) on the command line of a shell window or launch the Codessa file directly from Codessa-2.7.16 directory, either from the command line or from a file browser(launching with the mouse in a file browser only works if the login scripts have been edited as above). --------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- To get started with Codessa, try the following example (useful for illustration purposes only): 1) Launch Codessa On Windows, 2) Select "Data->Load..." from the main menu 3) In the "Select an Existing CODESSA Input File" dialog, select the file examples/ampac.inp in the Codessa-2.7.16 directory. This is a text input file containing a names, Ampac output file path, two properties ("BP" and "MP") and one "extra" descriptor ("LOGP") for each of 25 mono-substituted benzene molecules 4) In the "Columns" dialog, select the "Header" radio button for the "First Line" radio button group, verify the number (5) and types of columns and then select the "Ok" button 5) Select "Data->Sets..." from the main menu 6) In the "Set" dialog, select the "Structures (*ampac.inp) set and then select the Rename button 7) In the "Rename" dialog, change the set name to "MSB_All" and then select "Ok" 8) In the "Sets" dialog, select the "New" button 9) In the "New" dialog, enter "MSB_Train_1" for the "Set's name" and select the "Structures" radio button and then select "Ok" 10) In the "Compose set" dialog, add the first 20 structures of the "Source set" "MSB_All" to the "Target set" "MSB_Train_1" and then select "Ok" 11) In the "Sets" dialog, select the "New" button again 12) In the "New" dialog, enter "MSB_Predict_1" for the "Set's name" and select the "Structures" radio button and then select "Ok" 13) In the "Compose set" dialog, add the last 5 structures of the "Source set" "MSB_All" to the "Target set" "MSB_Predict_1" and then select "Ok" 14) In the "Sets" dialog, select the "Close" button 15) Select "Descriptors->Calculate->Molecule..." from the main menu 16) In the "Calculate descriptors" dialog, make sure the "Calculate all descriptors" checkbox is checked and then select "Ok" 17) In the "Select set" dialog, select the "MSB_All" set of structures just loaded and then select "Ok" 18) After several seconds, Codessa will have calculated over 400 descriptors for each molecule in the set "MSB_All" 19) Select "Correlate->Heuristic..." from the main menu 20) In the Heuristic "Options" dialog, set the "Maximum number of descriptors" to 3 and then select "Ok" 21) In the "Heuristic" dialog, select "BPC" as the "Property to fit", "MSB_Train_1" as the set of structures and "All descriptors" as the "Set of Descriptors" and then select "Start" 22) After several seconds, Codessa will have calculated the 11 "best" correlations found using the specified criteria 23) In the "Select correlations to save in set "BPC correlations"" dialog, select the first correlation and the last correlation and then select "Ok" 24) Select "Predict->View correlation..." from the main menu 25) In the "Correlation" dialog, double click on either correlation to get a "Status" window summarizing the correlation. Also, try clicking on the other buttons in the dialog to get more information about the currently selected correlation. For example, clicking on the "Plot" button will display a plot window of calculated (predicted) BPC values versus the experimental BPC values used as input for the currently selected correlation's set of training structures. For both correlations, use the "Rename" button to append " MSB_Train_1" to the their names as a convenience for recalling their training set of structures. 26) Select "Predict->Predict property..." from the main menu 27) In the "Select correlation" dialog, select "BPC correlations" for the "Set" and select the first correlation and then select "Ok" 28) In the "Select set" dialog, select the "MSB_Predict_1" set of structures and then select "Ok" 29) A text window showing the predicted BPC values versus the experimental input values is shown 30) Select "Plot->Prediction..." from the main menu 31) In the "Select correlation" dialog, select "BPC correlations" for the "Set" and select the first correlation and then select "Ok" 32) In the "Select set" dialog, select the "MSB_Predict_1" set of structures and then select "Ok" 33) A plot window showing the predicted BPC values versus the experimental input values is shown 34) Save your work as a Codessa project file by selecting "File->Save..." from the main menu 35) In the "Specify a New or Existing CODESSA Project File" dialog, save your project file as "myampac.cod" in the same directory as the ampac.inp file from which it started. For reference, a similar project file "ampac.cod" is included in the Codessa distribution. 36) Select "File->New" from the main menu 37) Select "File->Open..." from the main menu 38) In the "Select an Existing CODESSA Project File" dialog, open the "myampac.cod" file saved previously to load the previously saved project for further investigation of Codessa ... ---------------------------------------------------------------------------------------------
