Hi Ralf,<div><br></div><div>Thanks a lot for your help. I changed the order and it works now. But I am wondering why? Is that means the .bashrc script will read lines from down to up which allow it to see the line of source for phenix first?</div>

Dear all,<div><br></div><div>It&#39;s long story:</div><div><br></div><div>At beginning, I have phenix installed. I do not have CCP4 installed. Then I run &quot;phenix.phaser params.eff&quot; to call phenix run phaser from script params.eff. It works well. </div>



<div>Then, I installed CCP4 with its own phaser inside. Then I run again &quot;phenix.phaser params.eff&quot;. The computer start to import files (should be some libraries and supporting files, not input data) from CCP4 installation directory. It seems so strange for me. </div>



<div><br></div><div>And because some of the .so files in CCP4 directory are for 32bit, phenix.phaser gave me error message: wrong ELF class: ELFCLASS32 and refused to keep running. I guess I could solve this problem by copying the same .so file in phenix directory into CCP4&#39;s directory. <br>



<br>What I really want to know is why this happen. Is that the installation of CCP4 changed some kinds of PATH variables for phenix? How could I fix by giving a right path again? </div><div><br></div><div>I would appreciate to any help. Thanks a lot guys!</div>
