- VirtualBox is a program that allows you to run multiple operating systems (guests) on one computer (the host computer). You may need to transfer files between the host and the guest. It’s easy to set up in Windows guests, but tricky in Ubuntu guests.
Type a name for the new virtual machine. Since I am planning to install Ubuntu 14.04, I'll enter 'ubuntu1404'. Note that VirtualBox automatically changes 'Type' to Linux and 'Version' to 'Ubuntu (64 bit)'. These two options are exactly what we need.
The memory size depends on your host machine memory size. In my case, I have 12GB physical RAM. I like to allocate as much as possible for Ubuntu but leave some for my Windows host machine. I pick 8192 MB for my Ubuntu. Note that VirtualBox will create a swap partition with the same amount space as base memeory you have entered here. So later when you are selecting the size of the virtual hard drive, make sure it is large enough since the hard drive will be splitted into root (/)and swap partitions. The root partition contains by default all your system files, program settings and documents.
Accept the default 'Create a virtual hard drive now' and click 'Create' button.
Continue to accept the default 'VDI' drive file type and click 'Next' button.
Change the storage type from the default 'Dynamically allocated' to 'Fixed size' to increase performance.
For the virtual hard drive space, the default value is 8GB which is too little for RNA-Seq analysis. I'll pick 100GB since I have plenty of space in my hard disk. You want to choose a good size for your RNA-Seq analysis. If you realize the drive space is not large enough, you'll need to go over these steps again to create another virtual machine.
Click 'Create' button and VirtualBox will generate Ubuntu virtual machine.

Since Tophat program can take an advantage of multiple processors/threads, it is a good idea to specify a large number of processors in virtual machine (default value is 1).

Now you can click 'OK' button to continue.
