Dear All, I recently downloaded and installed phenix 1.7-1-743 on Ubuntu system. I need to run the command " source/usr/local/phenix**/phenix_env.sh" each time to launch the program when running as a command line. If I close that terminal and type the command in a new terminal, it is giving the reply "command not found". How does one set paths so that phenix.refine will be recognized in a new terminal window? I got some suggestiions to edit either ~/.bashrc or ~/.bash_profile and add the appropriate "source" command to it. But when I edit .bashrc phenix is automatically executed when I open a new terminal. I want to run phenix by typing command like "phenix.refine xx.pdb xx.mtz". Please let me know which file I should edit to get this. If possible can any ubuntu user send me a copy of the .bashrc file/or any other required file with environment path for phenix. Thank you for your time. Jobi
