Question: "I get a "permission denied" response when I run the Perl script (./c3540_runfs_stuckat_N15.run command).
Answer: Possible solutions:
1- Have you set the permissions correctly? chmod 755 c3540_runfs_stuckat_N15.run
2- Have you updated your .cshrc file to include FastScan bin directory: if ( `uname` == Linux ) then setenv PATH /home/software/mentor/2007/linux64/dft_2007_1_10/bin:$PATH endif
3- Edit the Perl script. Change "fastscan" to "/home/software/mentor/2007/linux64/dft_2007_1_10/bin/fastscan"
4- Instead of using the Perl script, copy the system command and run it in a shell window: /home/software/mentor/2007/linux64/dft_2007_1_10/bin/fastscan -nogui ....

Question: After modifying the dofile for ordering and compression, it gives me a statement "cannot find file pattern". What's wrong?
Answer: You did not add the ordering and compression commands after the patterns were generated so there is no data for the program to order or compress. Locate the pattern generation code in the dofile and add it after that line and before you export the results to files. You must add the code manually at some point in the tutorial.

Question: How can I view the output files?
Answer: You can view the files by entering vi , transfer the files to your computer and view it using Wordpad, or use xemacs .

Question: I don't like having to rename all my files for every execution. Is there an easier way?
Answer: You can edit the output filenames in the dofile and save the dofile under a different name. Be sure you also edit the script to access this file and modify the log file as well to prevent the script from overwriting the files. If you're really lazy, you can copy and paste the command in the script and have it run the command multiple times using multiple names after making multiple dofiles…

Question: What number should I set for multiple detection in the dofile?
Answer: Any number between 2 and 15 should work. Remember to remove the flags for ordering and compression by commenting them out when you do.
