Hi Engin, I created the file as you mentioned earlier, but I am having some problems with it. If I keep the "./sc_radii.lib" portion, I get the following error message: File: "./sc_radii.lib" Cannot be opened for reading >>>>>> CCP4 library signal ccp4_general:Cannot find input file (Error) raised in ccp4setenv <<<<<< Last system error message: No such file or directory sc: Cannot find input file sc: Cannot find input file Times: User: 0.0s System: 0.0s Elapsed: 0:00 I also tried removing the sc_radii.lib section, and I got the following error message: >>>>>> CCP4 library signal ccp4_general:Use: <logical name> <file name> (Error) raised in ccp4fyp <<<<<< sc: Use: <logical name> <file name> sc: Use: <logical name> <file name> Times: User: 0.0s System: 0.0s Elapsed: 0:00 ./sc.sh: line 5: MOLECULE: command not found ./sc.sh: line 6: CHAIN: command not found ./sc.sh: line 7: CHAIN: command not found ./sc.sh: line 10: END: command not found ./sc.sh: line 11: eof: command not found I am not sure what I am doing wrong with this script, so can you please give me some pointers? I attached the script I'm using for your convenience.
