99p

There a lot of problems that arise whenever you start relying on computers for your work.

Here are 99 random problems you'll probably never run into. When you do though, you'll be glad you have this list. Solutions to various problems will be kept here until a more permanent resting place is found.

nmrDraw Troubleshooting: Having problems with a "segmentation fault" error? Especially if you're on one of the newer workstations? Try checking your memory limits. Type "ulimit -a" for information. The number of open files should be set to 1024. You can do this by typing "ulimit -n 1024". If it is higher, you'll almost always get a segmentation fault. This was first discovered on macs, but it also holds true for linux based systems. EDIT: "ulimit -n 1024" only works for the currently open terminal window. It will reset as soon as you open a new terminal. If you want to set this limit permanently, you can add the function to your .bashrc file in your home directory. This will set the limit in every new terminal window you open.
